1. 3x – 7 = 8

+ 7 +7

3x = 15

3 3 x=5

2. 14x -2 = 3x + 53

14x – 2 = 3x + 53

+2 +2

14x = 3x + 55

-3x -3x

11x = 55

11 11 x=5

3. 8x + 4 (6 + x) = 3 (x – 7) + 10x

8x + 24 + 4x = 3x – 21 + 10x

12x + 24 = -7x - 21

-24 -24

12x = -7x - 25

+7 +7

19x = -25 x = 44

-19 -19

4. 1.4x + 2.6 = 0.6x + 1.16

-1.16 -1.16

1.4x + 2.6 = 0.6x + 1.16

-1.4 -1.4

1.44 = -0.8x x = -1.8

0.8
