Sagot :
bonjour
8 y - 2 y + 3 = 0
6 y = - 3
y = - 3/6 = - 1 /2
2/3 + 2 k /4 = 9
6 k/12 = 108/12 - 8/12
6 k = 100
k = 100/6 = 50/3
Bonsoir,
Résoudre les équations :
- 8y-(2y-3) = 9
- 8y-2y+3 = 9
- 6y+3 = 9
- 6y = 9-3
- 6y = 6
- y = 1
- 2÷3+2k÷4 = 9
- 4+3k = 54
- 3k = 54-4
- 3k = 50
- k = 50/3
Bonne soirée.
