7(x + 4) - 8(x + 3) = 5(2x - 1)
7x + 28 - 8x - 24 = 10x - 5
-x + 4 = 10x - 5
-11x + 4 = -5
-11x = -9
x = 9/11

7(x + 4) - 8(x + 3) = 5(2x - 1)
7x + 28 - (8x + 24) = 10x - 5
7x + 28 - 8x - 24 = 10x - 5
- x + 4 = 10x - 5
- x + 4 + x = 10x - 5 + x
4 = 11x - 5
4 + 5 = 11x - 5 + 5
9 = 11x
9 / 11 = 11x / 11
9 / 11 = x
