coucou
exercice 3
5(3x-2)=2(x+1)
15x-10=2x+2
13x-10=2
13x=12
x= 12/13
-2(x+3)=3(2x-1)
-2x-6=6x-3
-8x = 3
x= 3/-8
2(x-1)=4(3x+1)-12x
2x-2=12x+4-12x
2x-2=4
2x=6
x=6/2
x=3
x+3/4=1/5
x= 1/5 - 3/4
x= 4/20 - 15/20
x= -11/20
x/6 = 4
x=4*6
x= 24
x/3=4/7
x= 4/7 *3
x= 12/7
2/x = 3/4
2= 3/4 * x
2/(3/4)=x
8/3 =x
voila j espere t avoir aider
