Question

I'm having trouble finding the value of x for

Answer 1

x for what?

Answer 2

Sorry, I accidently sent it before I was done typing. I'm trying to find the value of x for 3(x+1)-5x= 12-(6x-7)

Answer 3

First distribute

3(x+1)-5x= 12-(6x-7)

3x+3-5x= 12-6x+7

and then combine like terms

3x+3-5x= 12-6x+7

-2x+3= -6x+19

I'll let you finish up

Answer 4

From -2x + 3= -6x+ 19 I subracted three from both sides to get

-2x= -6x+16

From there, I added -6x to both sides to get

-8x = 16, and I lastly divided them by negative 8 to get

-2. But when I checked it over and inserted the -2 it didn't work. Can someone point out what I did wrong? -_-

Answer 5

you made an error when you went from -2x= -6x+16 to -8x = 16

Answer 6

you do add 6x to both sides, that much is correct

Answer 7

however, -2x + 6x = 4x and not -8x

Answer 8

Oh! Thank you!

Answer 9

you're welcome
