1. - 2x - 3 = 6 + x 2x - x = 6 + 3 x = 9

2.

- 2x + 1 = 6 2x = 6 - 1 x = 5 / 2

3.

- 2(2x - 3) = 6 + x 4x - 6 = 6 + x 4x - x = 6 + 6 3x = 12 x = 12 / 4 x = 3

4.

- 4(x - 10) = - 6(2 - x) - 6x 4x - 40 = - 12 + 6x - 6x 4x = - 12 + 40 4x = 28 x = 28 / 4 x = 7

5.

- 3 / 4(2x + 4) = x + 19 6x + 12 = 4x + 76 6x - 4x = 76 - 12 2x = 66 x = 66 / 2 X = 33

6.

- (X - 1) / 6 - (X - 3) / 7 = - 1 7X - 7 - 6X + 18 = - 42 X + 11 = - 42 X = - 42 - 11 X = - 53

7.

- (X - 3)4 = (X - 2) / 5 5X - 15 = 4X - 8

5X - 4X = - 8 + 15 X = 7

8.

- (X - 7) / 5 = (X - 2) / 3 3X - 21 = 5X - 10 3X - 5X = - 10 + 21 - 2X = - 11 X = - 11 / - 2 X = 11 / 2

9.

- (X - 1) / 4 - (X - 5)36 = (X + 5) / 9 MCM = 36 9x - 9 - 4x + 20 = 4x + 20 5x + 11 = 4x + 20 5x - 4x = 20 - 11 x = 11

10.

- (x + 1) / 3 - (x - 2) / 2 = (x + 6) / 6 mcm = 6 2x + 2 - 3x + 6 = x + 6 - x + 8 = x + 6 - x - x = + 6 - 8 - 2x = - 2 x = - 2 / - 2 x = 1.
