Best ResponseYou've already chosen the best response.0So you are solving for x. Meaning you need to isolate the xvariable. What is your understanding of this Q so far?

Best ResponseYou've already chosen the best response.0ok start by distributing again

Best ResponseYou've already chosen the best response.0^ Must use the distributive property first. (To get rid of those complex parenthesis!)

anonymous

Best ResponseYou've already chosen the best response.0You need to use the distributive property on both sides of the equation first. 2(2x+5) and 3(x1)

Best ResponseYou've already chosen the best response.0yes! If we apply the distributive property of multiplication over addition at both sides, we get: 4x 10 3 = 3x +3

Best ResponseYou've already chosen the best response.0When you're in debt by $10, and get another loan for $3, you're in a total of 13$ of debt.

Best ResponseYou've already chosen the best response.0Now isolate the x from either side… you'll still get the same answer regardless of which side you isolate the x with. (I'd go with the easier side)

Best ResponseYou've already chosen the best response.0How would I do that?

anonymous

Best ResponseYou've already chosen the best response.0You should then get 4x10=3x+3 Then get variables and constants on different sides of equation 4x+3x=3+10 1x = 13 Divide both sides by 1 Your answer should be x = 13 or D

Best ResponseYou've already chosen the best response.0try to subtract 7x from both sides, please

anonymous

Best ResponseYou've already chosen the best response.0No, subtract three from both sides then you can divide. (Remember we CANNOT divide/multiply if there are other constants)

anonymous

Best ResponseYou've already chosen the best response.0Sorry I ran out of room but we're almost done… We would get: 16 = 7x

Best ResponseYou've already chosen the best response.0I'm not to sure how to divide it when it is a negative number.

anonymous

Best ResponseYou've already chosen the best response.0@Aureyliant I think you messed up somewhere because there is no way that the answer is 2 @FEARLESS_JOCEY look back at my comment and look at how io explained it i got the correct answer

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yes… you did. The answer is x = 16. I checked my work and I didn't see anything incorrect.

Best ResponseYou've already chosen the best response.0@Michele_Laino Do you see where I may have gone wrong?

anonymous

Best ResponseYou've already chosen the best response.0if you divide 16 by 7 you get 2.28 You went wrong by adding positive 4x to 3x and getting positive 7x when it should have been positive 1x

Best ResponseYou've already chosen the best response.0I'm pondering...@Aureyliant

anonymous

Best ResponseYou've already chosen the best response.0You're supposed to take the inverse of 4x = +4x. When you take it to the other side of the equation, it must become the opposite sign.

anonymous

Best ResponseYou've already chosen the best response.0Oh! I see where i went wrong. It was supposed to be 3x + 4x = 1x.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0I understand that but 3x did not change signs and it should have become 1x instead of positive 7x You also subtracted 3 from 10 and got 013 and then you subtracted 3 again

Best ResponseYou've already chosen the best response.0I forgot the negative three. I apologize.

Best ResponseYou've already chosen the best response.0I got thise expression: 4x13=3x+3 then adding 4x to both sides, we get: 13=x+3

Best ResponseYou've already chosen the best response.0See you guys are forgetting to cross out the three after you have moved it to the opposite side of the equation and you are ending up with an extra 3

anonymous

Best ResponseYou've already chosen the best response.0@Aureyliant you have already moved the 3 over to get 13 you do not need to subtract it again to get 16

anonymous

Best ResponseYou've already chosen the best response.0No… I didn't. The answer is B.

anonymous

Best ResponseYou've already chosen the best response.0I'm not sure if it is B or D now. Lol, I'm so confused

anonymous

Best ResponseYou've already chosen the best response.0It's 100% B. I didn't already subtract 3 to get 13… that was an earlier step with another 3. http://prntscr.com/7e7rjb

Best ResponseYou've already chosen the best response.0I think they set it up that way to make it confusing for the student.

anonymous

Best ResponseYou've already chosen the best response.0@Aureyliant look back at your quation you subracted 3 to get 13, but then you subtracted the 3 again to get 16 but you are not suppossed to because you gave already used it
