G= 3(4x-2) calcule G lorsque :

x = 5
4x - 2 =7
12x =11
6x =5
2x-1 = 3
3x=25

Sagot :

si x=5
G=3(20-2)
G=3*18
G=54
si 4x-2=7
G=3(7)=21
si12x=11
je distribue:(3*4x)+(3*(-2)
donc G=12x-6
G=11-6=5
je reflechis pour la suite

Sauf erreur, voilà ...

1) x = 5 
G = 3 x 18 => G = 54

2) 4 x – 2 = 7 
G=3 x 7 => G = 21 

3) 12 x = 11 
G = 11 – 6 => G = 5

4) 6 x = 5 
G = 10 – 6 => G = 4

5) 2 x – 1 = 3 
G = 6 x 3 => G = 18

6) 3 x = 25
G = 100 – 6 => G = 94
