bonsoir qui pourrais m'aider a poser ce calcul 5x+3=2x-3 x/2+11=13 merci d'avance bonne soirée

bonjour

5 x + 3 = 2 x - 3

5 x - 2 x = - 3 - 3

3 x = - 6

x = - 6/3 = - 2

x/2 + 11 = 13

0.5 x + 11 = 13

0.5 x = 13 - 11

0.5 x = 2

x =  4

Bonsoir,

♣️1) 5x + 3 = 2x - 3

5x - 2x = - 3 - 3

3x = - 6

x = - 6/3

x = - 2

2) x/2 + 11 = 13

x + 22 = 26

x = 26 - 22

x = 4
