Answer 2

Its 3? I got 2.

Answer 3

First, distribute the 2 into the x and 4 and distribute the negative 1 into the x and 1. so you get :
2(x+4) - (x+1)=10
2x+8-x-1= 10
then group like terms:
x+7=10
finally subtract 7 from 10 to get :
x=3.

Answer 4

Answer 6

you did't include the -1 when you distibuted the negative 1. you just wrote:
2x+8-1x=10
instead of:
2x+8-1x-1=10.
