1) -5x + 10 = -2x - 8
2) 7x + 14 = 5x - 22
3) -3 + 2x - 6 = 3 - 4x
4) 2(x - 3) + 3(4 - x) = 5
5) 2(x + 4) - 5(x + 3) = 2
6) 3(x - 4) - 2(2x - 5) = -4
7) -2(x + 3) + 4(2x +3) = -6
8) (3 - 2x) - (x + 4) - (2x + 5) = (3x - 4) - (5x + 7)
9) - (4 - 2x) - (2x + 4) = (3x - 1) +(2x - 5) - (7 - 3x)
10) 2(x - 7) - (x + 2) = 4(x + 3) + 2(x - 9)
11) -3(x +6) - 6(2x + 8) = -2(4 - x) + 9(x + 8)
12) 4 - 5(3 - x) = -x - (3 - 2x)
