Explications étape par étape

Bonsoir

6 = 20x + 10

20x = 6 - 10

x = -4/20

x = -1/5

6 - 3x = 10x

10x + 3x = 6

13x = 6

x = 6/13

16 + 8x = 14x + 13

14x - 8x = 16 - 13

6x = 3

x = 3/6

x = 1/2

(4x + 8)/(3x) = 2

3x # 0

x # 0

4x + 8 = 2 * 3x

4x + 8 = 6x

6x - 4x = 8

2x = 8

x = 8/2

x = 4

(8x - 2)/(6 + 9x) = 0

2(4x - 1)/[3(2 + 3x)] = 0

2 + 3x # 0

3x # -2

x # -2/3

4x - 1 = 0

4x = 1

x = 1/4

3x = (4x - 5)/6

3x * 6 = 4x - 5

18x - 4x = -5

14x = -5

x = -5/14
