Answer 1

x = 0

Explanation:

6(x + 1) -5x = 8 + 2(x - 1)

6x + 6 - 5x = 8 + 2x - 2

6x - 5x - 2x = 8 - 2 - 6

- x = 0

Answer 2

x = 0

Explanation:

6(x + 1) - 5x = 8 + 2(x - 1) =

6x + 6 - 5x = 8 + 2x - 2 =

x + 6 = 6 + 2x

6 - 6 = 2x - x

0 = x

check it...

6(0 + 1) - 5(0) = 8 + 2(0 - 1)

6(1) - 0 = 8 + 2(-1)

6 - 0 = 8 - 2

6 = 6 (correct)...so it checks out

x = 0 <===
