Bonsoir,
4/3 - 3x = 2/15
4/3 - 2/15 = 3x
(4*5)/(3*5) - 2/15 = 3x en mettant au même dénominateur
20/15 - 2/15 = 3x
18/15 = 3x
(18/15)/3 = x (a/b) /c = a / (bc)
x = 18/45
x = (9*2) / (9 * 5) = 2/5
Bonne soirée

Bonsoir,4/3 - 3x = 2/15
3x = 4/3 - 2/15 = 20/15 - 2/15 = 18/15
3x = 18/15 ÷ 3 = 18/15 × 1/3 = 18/45
18/45 = ( 18 ÷ 9 ) / ( 45 ÷ 9 ) = 2/5
Bonne soirée.
