A = 4 * t + 4 * 1 = 4t + 4

 

B = 5 * x + 5 * 7 = 5x + 35

 

Ainsi de suite....

A=4t+4                                                 B=5x+35

C=-6a+-6                                             D=10z-5

E=-12y+6                                             F=-8b+28

G=m au carré-5m                                 H=-t au carré+5t

I=7y+6y+18                                           J=3x-12+12x
