Bonjour :
c)
3/5x + 1/5 = 2/5x - 1/5
3/5x - 2/5x + 1/5 + 1/5 = 0
1/5x + 2/5 = 0
5(1)/5(5x) + 5x(2)/5x(5) = 25x(0)/25x
5/25x + 10x/25x = 0/25x
5 + 10x = 0
10x = -5
x = -5/10
x = -1/5
d)
3x + 4/3 = 2x + 1/6
3x - 2x + 4/3 - 1/6 = 0
x + 8/6 - 1/6 = 0
x + 7/6 = 0
6(x)/6 + 7/6 = 6(0)/6
6x/6 + 7/6 = 0/6
6x + 7 = 0
6x = -7
x = -7/6
J’espère t'avoir t'aider
