RESOUDRE LES EQUATIONS SUIVANTES : MERCI BEAUCOUP D'AVANCE

3 ) 5x −1 = 2x +4;
4 ) 2(x −1)−3(x +1) = 4(x −2);
5 ) 5(3x −1)−(1−2x) = 3(5x −2);
6)3sur2x +4 = 2x −5;

Sagot :

INDIANAAA
A) 5x-1=2x+4
5x-2x=4+1
3x=5
x=5sur3
B)2(x-1)-3(x+1)=4(x-2)
2x-2-3x-3=4x-8
-x-5=4x-8
-x-4x=-8+5
-5x=-3
x=3sur5
C)5(3x-1)-(1-2x)=3(5x-2)
15x-5-(1-2x)=15x-6
-5-1+2x=-6
-6+2x=-6
2x=0
x=0
D)3sur2x +4=2x-5
