Réduire les expressions suivantes
I= 3×(5× x + 1) -2
I = 3 * (5x + 1) - 2
I = 15x + 3 - 2
I = 15x + 1
j=6×y+7×y
J = 6y + 7y
J = 13y
h=4×z - z+2×z
H = 4z - z + 2z
H = 5z
2) o= 9×x - 6 × x
O = 9x - 6x
O = 3x
p= 13×a+8×a+a
P = 13a + 8a + a
P = 22a
q= b+5×b
Q = b + 5b
Q = 6b
r=26×c +4×c - 9 × c
R = 26c + 4c - 9c
R = 21c.
