A) 3 x + 5 = 4 ⇒ 3 x = 4 - 5 ⇒ 3 x = - 1 ⇒ x = - 1/3
b) 7 x + 8 = 14 x ⇒ 14 x - 7 x = 8 ⇒ 7 x = 8 ⇒ x = 8/7
c) 5 x - 3 = 7 + 5 x l'égalité n'est pas vraie

Bonjour,
Résoudre :
a.3x +5=4
3x + 5 - 5 = 4 - 5
3x = -1
3x/3 = -1/3
x = -1/3
b.7x +8 =14x
7x + 8 - 7x = 14x - 7x
8 = 7x
8/7 = 7x/7
x = 8/7
c. 5x -3 = 7+5x
5x - 5x = 7 + 3
0 = 10
