bonjour

Programme A

x

x - 5

7 ( x - 5 ) = 7 x - 35

7 x - 35 - 2 x

=  5 x - 35

avec  6  = 5 * 6 - 35 = 30 - 35 = - 5

avec - 4  = 5 * -4 - 35 = - 20 - 35 = - 55

Programme B  

x

- 3 x

- 3 x - 5

= - 3 x - 5

avec  5  = 5 * - 3 - 5 = - 15 - 5 = - 20

avec - 3 =  - 3 * - 3 - 5 = 9 - 5 = 4

5 x - 35 = - 3 x - 5

5 x + 3 x = - 5 + 35

8 x =  30

x = 30/8 =   3.75

il faut choisir  3.75
