résoudre chaque équation : a) 5x-3=6-3x b) 7-4x=-3+2x c)3(5-2x)=7-4x d)3-(2x-4)=x+7 merci!! :)

a) 5x-3=6-3x -> 5x+3x= 6+3 -> 8x=9 -> x=9/8
b) 7-4x=-3+2x -> 7+3=2x+4x -> 10=6x => x=10/6=5/3
c)3(5-2x)=7-4x => 15-6x=7-4x => 15-7=-4x+6x => 8=2x => x=4
d)3-(2x-4)=x+7 => 3-2x+4=x+7 => 3+4-7=x+2x => 3x=0 => x=0

5x-3=6-3x
5x +3x = +3 +6
8x=9
x=9/8

7-4x=-3 + 2x
-4x -2x=-7 -3
-6x=-10
x=10/6 = 5/3

3(5-2x)=7-4x
15 -6x=7-4x
-6x +4x = -15 +7
-2x = -8
x = -8/2
x= 4 

3-(2x-4)=x+7
3-2x+4 = x +7
-2x +7 = x+7
-2x -x= -7 +7
-3x = 0
x = 0
