i’m so confused someone pls help

Answer 1

3x+3=-2x+2-4

5x=-5

x=-1

Answer 2

x = - 1

Explanation:

Given

3(x + 1) = - 2(x - 1) - 4 ← distribute parenthesis on both sides

3x + 3 = - 2x + 2 - 4, that is

3x + 3 = - 2x - 2 ( add 2x to both sides )

5x + 3 = - 2 ( subtract 3 from both sides )

5x = - 5 ( divide both sides by 5 )

x = - 1
