Bjr,
- 3x - 2x = - 3 - 5
- 5x = - 8
x = 8/5
4x = - 48
x = -48/4 = -12
c) incomplet
d) 4x - 10x = 5
- 6x = 5
x = -5/6
3 * x + 3 * 2 - 5 * 3 - 5 * x = 0
3x + 6 - 15 - 5x = 0
- 2x - 9 = 0
- 2x = 9
x = -9/2.
bonjour
a) - 3 x + 5 = 2 x - 3
- 3 x - 2 x = - 3 - 5
- 5 x = - 8
x = 8 /5
b ) 4 x = - 48
x = - 48/4 = - 12
c) manque quelque chose
d) 4 x - 5 = 10 x + 1
4 x - 10 x = 1 + 5
- 6 x = 6
x = - 1
e) 3 x + 6 - 15 - 5 x = 0
- 2 x - 7 = 0
- 2 x = 9
x = - 9 /2
