Розв'язання:

4x = 24 + x

3x = 24

x = 8

8x - 8 = 20 - 6x

8x + 6x = 20 + 8

14x = 28

x = 2

9 - 4x = 3x - 40

4x + 3x = 9 + 40

7x = 49

x = 7

0.6x - 5.4 = -0.5 - 3.3

0.6x = -0.5 + 5.4 - 3.3

0.6x = 1.6

x = 1.6 / 0.6

x ≈ 2.67

4.7 - 1.1x = 0.5x - 3.3

1.1x + 0.5x = 4.7 + 3.3

1.6x = 8

x = 8 / 1.6

x = 5

(5/6)x + 16 = (4/9)x + 9

(5/6)x - (4/9)x = 9 - 16

(15/18)x - (8/18)x = -7

(7/18)x = -7

x = -7 / (7/18)

x = -18
