p 1

x

3 x

3 x + 25

2 ( 3 x + 25 )

= 6 x + 50

6 x + 50 = 80

6 x = 80 - 50 = 30

x = 5

P 2

x

x + 10

11 ( x + 10 ) = 11 x + 110

11 x + 110 + 3

= 11 x + 113

11 x + 113 = 80

11 x = 80 - 113 = - 33

x = - 3

6 x + 50 = 11 x + 113

6 x - 11 x = 113 - 50

- 5 x = 63

x = - 63/5

il faut choisir - 63/5
