Bonsoir,
1) 3x-1+4(x-2)=5(2x-1)-(3x+5)
3x - 1 + 4x - 8 = 10x - 5 - 3x - 5
3x + 4x - 10x + 3x = - 5 - 5 + 1 + 8
0x --> Impossible
2) x+1/5=2x-1/3
x - 2x = - 1/3 - 1/5
15/15x - 30/15x = - 5/15 - 3/15
15x - 30x = - 5 - 3
- 15x = - 8
x = 8/15
3) 3x+1+7(2/3-2x/7)=5/7 x+2
3x + 1 + 14/3 - 14x/7 = 5/7x + 2
63/21x + 21/21 + 98/21 - 42/21x = 15/21x + 42/21
63x + 21 + 98 - 42x = 15x + 42
63x - 42x - 15x = 42 - 21 - 98
6x = - 77
x = - 77/6

Bonsoir,1) 3x-1+4(x-2)=5(2x-1)-(3x+5)

3x + 4x - 10x + 3x = - 5 - 5 + 1 + 8

2) x+1/5=2x-1/3
x - 2x = - 1/3 - 1/5
15/15x - 30/15x = - 5/15 - 3/15
15x - 30x = - 5 - 3
- 15x = - 8
x = 8/15
3) 3x+1+7(2/3-2x/7)=5/7 x+2
3x + 1 + 14/3 - 14x/7 = 5/7x + 2
63/21x + 21/21 + 98/21 - 42/21x = 15/21x + 42/21
63x + 21 + 98 - 42x = 15x + 42
63x - 42x - 15x = 42 - 21 - 98
