Boujours pouvez vous m aider : a) 3-(5x+1)=8x+(4-2x) b) 8-3(2x-4)=5x-(x+1) c) 4(2x-6)-8=5-(x-7)

a) 3-(5x+1)=8x+(4-2x)
3-5x-1 = 8x+4-2x
2-5x = 6x+4
6x+5x = 2-4
11x = -2
x = -2/11

b) 8-3(2x-4)=5x-(x+1)
8-6x+12 = 5x-x-1
20-6x = 4x-1
6x+4x = 20+1
10x = 21
x = 21/10

c) 4(2x-6)-8=5-(x-7)
8x-24-8 = 5-x+7
8x-32 = -x+12
8x+x = 32+12
9x = 44
x = 44/9
