Bonsoir,
a. 5x + 7 = 2x - 2
5x - 2x = - 2 - 7
3x = - 9
x = - 9/3
x = - 3
b. 3x + 2 = x - 10
3x - x = - 10 - 2
2x = - 12
x = - 12/2
x = - 6
a. 2x - 5 = 5x + 1
2x - 5x = 1 + 5
- 3x = 6
x = - 6/3
x = - 2
b. 3 - 7x = 3x + 2
- 7x - 3x = 2 - 3
- 10x = - 1
x = 1/10
a. 5x - 6 = - x + 3
5x + x = 3 + 6
6x = 9
x = 9/6
x = 3/2
b. 2x - 1/3 = 1
2x = 1 + 1/3
2x = 3/3 + 1/3
2x = 4/3
6x/3 = 4/3
6x = 4
x = 4/6
x = 2/3
