x+5/3 - 1-x/2 = 3+x/4
je suppose que les fractions inclus plusieurs termes ? :
(x+5)/3 - (1-x)/2 = (3+x)/4
(x+5)/3 - (1-x)/2 - (3+x)/4 = 0
4(x+5)/12 - 6(1-x)/12 - 3(3+x)/12 = 0
4(x+5) - 6(1-x) - 3(3+x) = 0
4x + 20 - 6 + 6x - 9 - 3x = 0
4x - 3x + 6x + 20 - 9 - 6 = 0
10x + 5 = 0
10x = -5
x = -5/10
x = -1/2
en espérant t'avoir aidé.
