bonjour

3 x /4 + 5/6 = x

3 x /4 - x = - 5/6

9 x /12 - 12 x /12 = - 10/12

9 x - 12 x = - 10

- 3 x = - 10

x = 10/3

20 x /100 + 3 x /50 + 24  /25 = x

20 x /100 + 3 x /50 - x = - 24/25

20 x /100 + 6 x /100 - 100 x /100 =  - 96/100

- 74 x /100 = - 96/100

- 74 x = - 96

x = 96/74  = 48/37

5 x /12 + x /4 + 2/3 = x

5 x /12 + 3 x /12 - 12 x /12 = - 8/12

- 4 x = - 8

x = 2
