Réduire les expressions littérales suivantes :
L = 6x - 8 - 7x + 5
L = 6x - 7x - 8 + 5
L = - x - 3
M = -4 + 9x + 10 - 13x
M = 9x - 13x - 4 + 10
M = - 4x + 6
N = 2c + 4 – 3c + 6 - 2c + 8c - 8
N = 2c - 2c - 3c + 8c + 4 + 6 - 8
N = 5c + 2
0 = y² + 8y - 7 - 8y + 14 - 2y² + 3y
O = y² - 2y² + 8y - 8y + 3y - 7 + 14
O = - y² + 3y + 7.
