4(x+5)=10x+3
4x + 20 = 10x + 3
4x - 10 x = 3 - 20
-6x = -17
6x = 17
x = 17/6
En espérant t'avoir aidé.
1) 4(x+5) = 10x +3
4x +20 = 10x +3
4x -10x = -20 +3
-6x = -17
x = -17/6 - X - = + 17/6
réponse au calcul puis rédigement svp 1) 4(x+5)=10x+3
4(x+5)=10x+3
4x + 20 = 10x + 3
4x - 10 x = 3 - 20
-6x = -17
