1)7 - 4 = 9x - 103 = 9x - 103 + 10 = 9x13 / 9 = x

2)4x - 9 + x = 2x + 8 - x + 3 5x - 9 = 1x + 11 5x - x = 11 + 9 4x = 20 x = 20 / 4 x = 5

3)3x + 2 = 2x + 8 3x - 2x = 8 - 2 1x = 6 x = 6

4)4x + 2 = 5x - 11 4x - 5x = - 11 - 2 - 1x = - 13 x = - 13 / - 1 = 13

5)x + 3x + 5 = x + 3 + 2x + 6x + 3x - x - 2x = 3 + 6 - 5x = 46)5x - 14 = 3x + 8 - (x - 8)5x - 3x - x = 8 + 8 + 14x = 307)3x + 6 + 4x - 2 + 5x - 4 + 6x = 363x + 4x + 5x = 36 - 6 + 212x = 32x = 32 / 12x = 8 / 38)2(x + 3) = 3x - 82x + 6 = 3x - 82x - 3x = - 8 - 6 - 1x = - 14x = 14

9)2x - 5 = 5(x - 4)2x - 5 = 5x - 202x - 5x = - 20 + 5 - 3x = - 15x = - 15 / - 3x = 5

10)x + 3(x - 2) = 2x - 4x2 - 2x + 3x - 6 = 2x - 4x2 - 2x + 3x - 2x = - 4 + 6x2 - x + 2 = 0.
