3x - 2x - 2 - 1 = x - 3

4x + 5x + 3 + 5 = 9x + 8

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

21m + m - 12m - 3 = 10m - 3

et

3x + 2x + 4 + 3 = 5x + 7

INEQUATION

Bonjour,

Réduire les expressions:

3x−2−2x−1 = x-3

4x+3+5x+5 = 9x+8

2x−3−(−3x)−2 = 2x-3+3x-2= 5x-5

21m+m−6×2m−3 = 22 m-12 m-3= 10 m-3

3x+4+2x+3= 5x+7
