Bonjour

5 - (x – 3) = 4x - (3x – 8)

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

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

- 2x = 0

x = 0

2 + x - (5 + 2x) - 7 = 3x + 7

2 + x - 5 - 2x - 7 = 3x + 7

x - 2x - 3x = 7 + 7 + 5 - 2

- 4x = 17

x = - 17/4

4x + 3 - (x + 1) + 5 = 5x + 7

4x + 3 - x - 1 + 5 = 5x + 7

4x - x - 5x = 7 - 3 + 1 - 5

- 2x = 0

x = 0

2x + 1 - (2 + x) - 7 = 3x + 7

2x + 1 - 2x - x - 7 = 3x + 7

2x - 2x - x - 3x = 7 + 7 - 1

- 4x = 13

x = - 13/4

5(x - 1) + 3(2 - x) = 0

5x - 5 + 6 - 3x = 0

5x - 3x = 5 - 6

2x = - 1

x = - 1/2

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

7x + 28 - 3x - 6 = x + 7

7x - 3x - x = 7 - 28 + 6

3x = - 15

x = - 15/3

x = - 5

2(x - 1)-3(x + 1) = 4(x - 2)

2x - 2 - 3x - 3 = 4x - 8

2x - 3x - 4x = - 8 + 2 + 3

- 5x = - 3

x = 3/5.
