Sagot :
K = 7X - 2X = X (7-2) = 5x
L = 3y + 9y = y (3+9) = 12y
M = 8a - 12a = a (8-12) = -4a
N = 6b + b = b (6+1) = 7b
O = -10X + 3X = x (-10 + 3) = ......x
P = 8y - 20y = y ( ...- ...) = ... y
Bonjour :)
Réponse en explications étape par étape :
- Question : Simplifier les expressions suivantes :
K = 7x - 2x
K = x(7 - 2)
K = 5x
L = 3y + 9y
L = 3y(1 + 3)
L = 4 * 3y
L = 12y
M = 8a - 12a
M = 4a(2 - 3)
M = - 1 * 4a
M = - 4a
N = 6b + b
N = b(6 + 1)
N = 7b
O = - 10x + 3x
O = x(- 10 + 3)
O = - 7x
P = 8y - 20y
P = 4y(2 - 5)
P = - 3 * 4y
P = - 12y
Voilà
