Answer 4

what answer did you get?

Answer 5

Answer 6

x needs to be all by itself

Answer 7

Oh right. Hold on

Answer 8

Answer 10

what is 4(x+2) equivalent to when you distribute the 4 through?

Answer 11

4x + 11

Answer 12

OOPS

Answer 13

I meant 4x + 8

Answer 14

okay what do you do after you get that answer?

Answer 15

add 3 or subtract 4?

Answer 16

correct, so we have
2x - 3 = 4x + 8

Answer 17

now you would need to isolate the x

Answer 18

if you want x on the left side, you would add 3 to both sides (to move the -3 over)
also you would subtract 4x from both sides (to move the 4x over)

Answer 19

So now we have 2x = 4x + 11?

Answer 20

yup now you have to bring 4x to the other side so you can isolate the x-value

Answer 21

so now we have -2x + 11

Answer 22

why would it be -2x+11? where'd the equal sign go?

Answer 23

oops sorry. i meant to put the equal sgn

Answer 24

lol it's okay haha
so now your equation is -2x=11 what do you do to isolate x completely?

Answer 25

divide by -2

Answer 26

yup

Answer 27

x = -5.5

Answer 28

can you put it in decimal or do you have to leave it in fraction form?
