3x + 2(x + 3) = -2 + 4(x - 4)
3x + 2x + 6 = -2 + 4x - 16
5x + 6 = 4x - 18
x + 6 = -18
x = -24

3x + 2(x + 3) = -2 + 4(x - 4)
distribute
3x + 2x + 6 = -2 + 4x - 16
combine like terms
5x + 6 = 4x - 18
subtract 4x for both sides
x + 6 = -18
subtract 6 for both sides
x = -24

3x + 2(x + 3) = -2 + 4(x - 4)
3x + 2x + 6 = -2 +4x -16 (multiply out brackets)
5x + 6 = 4x - 18 (gather x's and other numbers)
x + 6 = -18 (gather x's on one side -4x from 5x))
x= -24 (take 6 from -18)
