1. 4.

3 ( 4 - 2 x ) = - 2 x

3 * 4 - 3 * 2 x = - 2 x

12 - 6 x = - 2 x Add 6 x to both sides

12 - 6 x + 6 x = - 2 x + 6 x

12 = 4 x Divide both sides by 4

3 = x

x = 3

5.

5.4 + 0.2 x = - 1.4 x + 8.6 Subtract 5.4 to both sides

5.4 - 5.4 + 0.2 x = - 1.4 x + 8.6 - 5.4

0.2 x = - 1.4 x + 3.2 Subtract 3.2 to both sides

0.2 x - 3.2 = - 1.4 x + 3.2 - 3.2

0.2 x - 3.2 = - 1.4 x Subtract 0.2 x to both sides

0.2 x - 0.2 x - 3.2 = - 1.4 x - 0.2 x

- 3.2 = - 1.6 x Divide both sides by - 1.6

- 3.2 / - 1.6 = x

2 = x

x = 2

6.

- 4 - 5 ( x + 8 ) =

- 4 - 5 * x - 5 * 8 =

- 4 - 5 x - 40 =

- 5 x - 44

7.

3 x + 4 ( x - 6 ) - 3 ( x - 7 ) =

3 x + 4 * x + 4 * ( - 6 ) - 3 * x - 3 * ( - 7 ) =

3 x + 4 x - 24 - 3 x + 21 =

4 x - 3
