2 + -1(x + 5) = 4x + -8

2 + -1(5 + x) = 4x + -8

2 + (5 * -1 + x * -1) = 4x + -8

2 + (-5 + -1x) = 4x + -8

-3 + -1x = 4x + -8

-3 + -1x = -8 + 4x

-3 + -1x + -4x = -8 + 4x + -4x

-3 + -5x = -8 + 4x + -4x

-3 + -5x = -8 + 0

-3 + -5x = -8

-3 + 3 + -5x = -8 + 3

0 + -5x = -8 + 3

-5x = -8 + 3

-5x = -5

x==1
