Question

Solve: 8x − 2(x + 1) = 7x + 8

Answer 1

8x + (-1)2(x + 1) = 7x + 8

Answer 2

use distributive property, for what is in the brackets.

a(b+c) = a(b) + a(c)

Then isolate x on one side of the equation

Answer 3

so

(-1)2(x+1) = -1(2)(x) + (-1)(2)(1)

Answer 4

distribute the -2 so you get 8x - 2x - 2 = 7x + 8. Now solve for x. I got -10

Answer 5

i got -10 too :D

Answer 6

8x-2x+2=7x+8
8x-2x-7x=8-2
-x=6
x=-6

Answer 7

how did you get the -10
