Merci de m'aider pour l'exercice 34 et 37: la question est: Résoudre chaque équation

Ex 34: a) 2x+3=1
= 2x=1-3
= 2x= -2
=x= -2/2
=x= -1

B) 2x-3=1
= 2x=1+3
=2x=4
=x=4/2
=x=2

C) 2(x+3)=1
=2x+6=1
=2x=1-6
=x= -5/2

D) 3x/7 +4=-8
= 3x/7 +28/7=-56/7
=3x+28=-56
=3x=-56-28
=3x=-84
=x=-84/3
=x=-28

Ex 37 : a) 3x-3+2x+6=0
=5x+3=0
=5x=-3
=x= -3/5
B) -5x-10+3x-9=7
=-2x-19=7
=-2x-19-7=0
=-2x=26
=x=-26/2
=x=-13

C) -4x+4-6x+10=0
=-10x+14=0
=-10x=-14
=x=14/10
=x=7/5

Voilà bon courage :)
