Vous pouvez m’aider je suis pas forte en équation

Hello !

a) 5x = 3x+3
5x-3x = 3
2x = 3
• x = 3/2

b) 8x = 12x+4
8x-12x = 4
-4x = 4
• x = -4/4 = -1

c) 4-7y = 10y
-7y-10y = -4
-17y = -4
• y = 17/4

d) 7x+1 = -4-x
7x+x = -4-1
8x = -5
• x = -5/8

e) 2+3x = 7-3x
3x+3x = 7-2
6x = 5
• x = 5/6

Bonne soirée !
