Best ResponseYou've already chosen the best response.1Subtract 2 from both sides first.

Best ResponseYou've already chosen the best response.1Now divide both sides by 5

Best ResponseYou've already chosen the best response.0but that comes out to 2.2... and it needs to come out as a whole number..

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1That would be  2.2 and it cannot come out as a whole number unless you copied the problem wrong.

Best ResponseYou've already chosen the best response.0okay.. the real question is.. 13=5m2 i didnt think it would natter if you flopped it around..

Mertsj

Best ResponseYou've already chosen the best response.1You didn't "flop it around". You changed 5m2 to its opposite. That's like saying, ok, I'll just change this 10 to 10

Best ResponseYou've already chosen the best response.0it still comes out 2.2...

Best ResponseYou've already chosen the best response.1\[\frac{15}{5}=\frac{5m}{5}\]

Best ResponseYou've already chosen the best response.0okay tell me if i get this right to this next question.. 15=2t11

anonymous

Best ResponseYou've already chosen the best response.0so would you add 15 to both sides?

Mertsj

Best ResponseYou've already chosen the best response.1Remember you are trying to get the variable by itself. The variable has been multiplied by 2 and then had 11 subtracted from it. How would you "undo" those things so that the variable can be by itself?

anonymous

Best ResponseYou've already chosen the best response.0so.. then would you do 2t then? so then you could get rid of it?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1You "undo" the stuff in reverse order. The variable was multiplied by 2 and 11 was subtracted. To undo that add 11 and then divide by 2

Best ResponseYou've already chosen the best response.0oh.. i see that now. sorry.. this is really frustrating..

Mertsj

Best ResponseYou've already chosen the best response.1Well I know it is but if you keep at it, all of a sudden the light will come on.

anonymous

Best ResponseYou've already chosen the best response.0yeah, after i figure out what to either use to "undo" then i got the rest of the problem.. its just i never know what number to either subtract from or add.. you know what i mean?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1I do know what you mean. Just always focus on getting the variable by itself by "undoing" the stuff. What did you get for this problem?

Mertsj

Best ResponseYou've already chosen the best response.1that was very good. Do you have another one?

Mertsj

Best ResponseYou've already chosen the best response.1Ok. What do you think comes first?

anonymous

Best ResponseYou've already chosen the best response.0and this is the part i mean i have troubles with.. like i never know if you would add 5bor 19..

Mertsj

Best ResponseYou've already chosen the best response.1I don't mean the solution. I just want you to identify the variable. Is it x or y or ...what is it?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Yes. Good. Now look at it. Is it multiplied or divided by something?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Exactly. So at some point we're going to have to reverse that by dividing by 7.

Mertsj

Best ResponseYou've already chosen the best response.1But first, was anything added or subtracted to or from the k?

anonymous

Best ResponseYou've already chosen the best response.0yeah because the problem is 7k5

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Yes you are correct but I want you to tell me specifically what the number is and whether it was added or subtracted.

anonymous

Best ResponseYou've already chosen the best response.0so for my question here 7k5=19 first i going to add 5 to 5 and 19 then rightt?

Mertsj

Best ResponseYou've already chosen the best response.15 is subtracted because it says 5 so you should add 5 to both sides.

Mertsj

Best ResponseYou've already chosen the best response.1Let me draw it for you in a different way

Mertsj

Best ResponseYou've already chosen the best response.1Now divide both sides by 7

anonymous

Best ResponseYou've already chosen the best response.0so the answer all together then would be, k=2

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Yes. Good. Do you have another one?

Mertsj

Best ResponseYou've already chosen the best response.1What are you going to do first?

Mertsj

Best ResponseYou've already chosen the best response.1What first to get x alone?

Best ResponseYou've already chosen the best response.0wait.. so like how would u figure that out.. like first step..

anonymous

Best ResponseYou've already chosen the best response.0so then 3 would go under the 107

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0then you would divide.. but what would u do to divide in this case?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1We could divide by 1/2 but did anybody ever teach you that dividing is the same as multiplying by the reciprocal?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1So dividing by 1/2 is the same as multiplying by 2. It might be easier to just multiply by 2

Best ResponseYou've already chosen the best response.0oh, i kinda see this noww

Mertsj

Best ResponseYou've already chosen the best response.1Do you have another one?

Best ResponseYou've already chosen the best response.0so first would you subtract 6 to 6 and the 4?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Subtract 6 from both sides.

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Well, we could divide by 1/5 or multiply by 5. Which do you choose?

anonymous

Best ResponseYou've already chosen the best response.0yeahh so then 10 *5?

anonymous

Best ResponseYou've already chosen the best response.0on my math homework now, i just finished 7 problems.. and before your help i couldn't even finish one.. THANKS!!!! :)

Best ResponseYou've already chosen the best response.1What is 1 dollar + 3 dollars

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Now what if I said that I don't want to write out dollars all the time so I am just going to use d What would 1d + 3d be?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1And supposing we would all agree that d means 1d then what would d+3d be?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1so now in your problem you have w + 3w What do you suppose that is?

Mertsj
 4 years ago
Best ResponseYou've already chosen the best response.1Exactly. So now your problem is 4w=20 How would you solve that?

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0divide by 4 so 20 divided by 4 would be 5

anonymous

Best ResponseYou've already chosen the best response.0so now theres this.. 3(y+5)=21

anonymous

Best ResponseYou've already chosen the best response.0yeahh, we did it before.. but i forgot all about it.. but im sure ill remember once i see it again..

anonymous

Best ResponseYou've already chosen the best response.0idkk.. not really.. lol

Mertsj

Best ResponseYou've already chosen the best response.1you have to "distribute' the 3 to the y and to the 5

Mertsj

Best ResponseYou've already chosen the best response.1Did you get the other one?

anonymous

Best ResponseYou've already chosen the best response.0soo would that be 5a+7=18?
