Bonjour
- 3/4 + 2x = 2x+1/2
2x - 2x = 1/2 + 3/2
0x = 4/2 impossible pas de solution
S = Ф
7x-1/4 = 2-3x/5
7x + (3/5) x = 2 + 1/4
(35x + 3x) / 5 = (8 + 1) / 4
(38/5)x = 9/4
x = (9/4) / (38/5)
x = (9 x 5) / (4 x 38)
x = 45 / 152
S = {45/152}

Bonsoir,
Il faut faire passer tous les x dans le même membre et les autres termes dans l'autre membre, puis diviser par le coefficient de x.
Cela n'est pas possible, donc l'équation n'a pas de solution.
Si tu as des questions, n'hésite pas ! =)
