1....

3/2x - 4/3 = 2/3x + 1/2

Kedua ruas dibagi dengan 6

3.3x - 4.2 = 2.2x + 1.3

9x - 8 = 4x + 3

9x - 4x = 3 + 8

5x = 11

x = 11/5

2....

3 1/2x - 4/5 = 3 1/2 - 2 1/5

7/2x - 4/5 = 7/2 - 11/5

7/2x = 7/2 - 11/5 + 4/5

Kedua ruas dikali 10

7.5x = 7.5 - 11.2 + 4.2

35x = 35 - 22 + 8

35x = 13 + 8

35x = 21

x = 21/35

x = 3/5

3....

4/3(x + 3) = 1/2(2x - 5)

Kedua ruas dikali 6

4.2(x + 3) = 3(2x - 5)

8(x + 3) = 6x - 15

8x + 24 = 6x - 15

8x - 6x = - 15 - 24

2x = -39

x = -39/2
