Best ResponseYou've already chosen the best response.0divide both sides by 3, and you have what?

Best ResponseYou've already chosen the best response.2First you would multiply 2 and x by 3 and you would get (6+3x)=12

Best ResponseYou've already chosen the best response.0I think it is easier to divide both sides by 3, then you have x+2=4

zzr0ck3r

Best ResponseYou've already chosen the best response.0but either way works :)

Best ResponseYou've already chosen the best response.0After the 3x =6 what do i do

Best ResponseYou've already chosen the best response.2divide 3x AND 6 by 3 to get x by itself, then you get the answer. x= ?

Best ResponseYou've already chosen the best response.0This is how I would do it. \[3(x+2)=12\] We want to get \(x\) by itself on one side. Firsts I would divide away the \(3\) \[\frac{3(x+2)}{3}=\frac{12}{3}\\\frac{\cancel{3}(x+2)}{\cancel{3}}=4\\ \\x+2=4\] Now we want to subtract \(2\) from both sides, so that \(x\) is by itself. \[x+22=42\\x=42\\x=2\]

Best ResponseYou've already chosen the best response.0Hi! I'm pretty new but I might be able to help... What you're looking at there in this equation is something called "Distributive property." see the 3(2+x) ? Thats' it! That's going to be the key to this problem. It gets its name from having to distribute whatever number is outside the parentheses. In this case, you would distribute the 3 into the 2, and the x. So take your three, and the two. Multiply them together. What do you get? 6. Now, do the same with the x.

Best ResponseYou've already chosen the best response.0Okay i get 3 if I do 3* X

Best ResponseYou've already chosen the best response.0Which part of my explanation are you confused by?

anonymous

Best ResponseYou've already chosen the best response.0Yep! Perfect! Do you know what you get when you multiply 3 and x together?

anonymous

Best ResponseYou've already chosen the best response.0I know that stuff but writing it out is confiding me

Best ResponseYou've already chosen the best response.0it is not that \(x=1\) it is \(x=1x\)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Not quite... In this case, we won't be treating it as a 1, instead we will treat it as just a plain x. In this case, all you would need to do is put a three next to the x! So you would end up with 3x : >

Best ResponseYou've already chosen the best response.0@enderkitty29 some people like to think if there being a 1 in front of an x when there is no coefficient.

anonymous

Best ResponseYou've already chosen the best response.0Okay can you show how i would write that please

anonymous

Best ResponseYou've already chosen the best response.0So far i have 3(2+x)=12 6+3 = 12

anonymous

Best ResponseYou've already chosen the best response.0Ah, you're very right zzr0ck... Forgot to take into account the other ways of looking at the problems.

anonymous

Best ResponseYou've already chosen the best response.0Wait a minute Kaitlyn, there is something a bit off about what you have so far. You are missing an x in the equation! Do you know where it should be?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Perfect! The x is a very important part of the equation. Without it, you won't be able to solve it : )

anonymous

Best ResponseYou've already chosen the best response.0Okay what is the next step

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Now, we want to try and get the x all by itself! In this case, we must subtract something from both sides. What do you think we should subtract?

anonymous

Best ResponseYou've already chosen the best response.0What happens to that 3 on the outside of the ()

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0The three is no longer there, since you multiplied the two numbers by three inside the parentheses. It's almost like canceling it out, so you don't need to worry about it anymore :)

anonymous

Best ResponseYou've already chosen the best response.0Okay so I subtract 3 from 3x and 12?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Nope, not the three. Make sure to remember your equation is 6 + 3x = 12.

anonymous

Best ResponseYou've already chosen the best response.0We are trying to get the x all by itself first. What do you need to take away from the left side of the equation to do this?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Perfect! Since you are going to subtract the 6 from the left side, you need to do this to the right side. What does our equation look like now?

anonymous

Best ResponseYou've already chosen the best response.03(2+x)=12 6+3x =12 6 6

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Perfect! So far, we should end up with 3x = 6

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Do you understand why its 6 on the right side?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Because whatever you do to one side you do to the other

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Right on! Now, only one more step. Almost done. Do you see the 3x? That means 3 * x

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0We still need the x by itself, so we need to get the three out of there somehow. Do you know how to do that?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Wonderful job! Thats correct!

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0So what do we end up with overall? What does our equation look like now?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yep! You got it! There is your answer : )

anonymous

Best ResponseYou've already chosen the best response.0Omg thank you!!!! Of its not to much to ask i need one more to be finished

anonymous

Best ResponseYou've already chosen the best response.0Thank you!!! 52(x4)=20

anonymous

Best ResponseYou've already chosen the best response.0Alright! Remember the thing we did in our last equation called distributive property? We are going to do that here again! What do you think we should do first?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Subtract 2 on each side?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Nope! I'll give you a hint. It has to do with the 2(x4).

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Remember what we did last time with the distributive property : )

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Nope! 2(x4). What do we do with the negative two?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yeah! What are we going to multiply?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Wonderful! So lets take the 2 and the x, and multiply them together. What do we get?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yeah! Now lets do 2 and 4.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Nope! Multiply them together, don't add. Remember what happens when you multiply two negatives with each other : )

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0It becomes a positive?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Right on! So what is 2 * 4 then?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yep! So what does our equation look like now that we distributed the 2?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.052(x4)=20 2x + 8 =20

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0You forgot two things! First, you forgot to keep the 5 in the equation : ) Second, there should be a negative in front of the 2x. So, our equation should look like this: 5  2x + 8 = 20

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0No worries, lets move on! Now, we will be doing something called "Combining like terms." This means to take numbers that are similar, and add them together! Do you see any similar numbers here?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Perfect! Now add those together, and what do you get?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0So how would i write that down

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Okay, good. Now that we added the 5 and 8 together, we are going to have 13  2x = 20

anonymous
 one year ago
Best ResponseYou've already chosen the best response.013  2x = 20 (it got cut off a bit, had to rewrite it)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Do you understand why we added them together and got what we got?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yes because we are trying to get x alone

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Perfect! What do you think we should do next?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0After that, what does our equation look like?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yep! There we go. What do we do now?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Perrrrrfect! Now, you can either leave it as 7/2 or 4.5

anonymous

Best ResponseYou've already chosen the best response.0What does the paper say?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yep! 3.5 That's what I ment lol. Finger slipped : )

anonymous

Best ResponseYou've already chosen the best response.0Its Okay Omg thank you so much!!!!!!!
