Hello,
11 + 2(x - 6) = 11 + 2 * x + 2 * -6 = 11 + 2x - 12 = 2x - 1
-3(2y - 4) - 2y = -6y + 12 - 2y = -8y + 12
7 - 4(8 - 2a) + a = 7 - 32 + 8a + a = 9a - 25
-15 - 9(-5 + 3b) = -15 + 45 - 27b = ....
-5(6 - 3z) - 9 + z = -30 + 15z - 9 + z = ........
12x - 4(6 - 3x) = 12x - 24 + 12x = 24x - 24

Bonjour,
L = 11 + 2(x − 6)
L = 11 + 2 * x + 2 * (-6)
L = 11 + 2x - 12
L = 2x - 1
M = − 3(2y − 4) − 2y
M = -3 * 2y - 3 * (-4) - 2y
M = -6y + 12 - 2y
M = -8y + 12
N = 7 − 4(8 − 2a) +a
N = 7 - 4 * 8 - 4 * (-2a) + a
N = 7 - 32 + 8a + a
N = 9a - 25
P = − 15 − 9(− 5 +3b)
P = -15 - 9 * (-5) - 9 * 3b
P = -15 + 45 - 27b
P = -27b + 30
Q = − 5(6 − 3z) − 9 +z
Q = -5 * 6 - 5 * (-3z) - 9 + z
Q = -30 + 15z - 9 + z
Q = 16z - 39
R = 12x − 4(6 − 3x)
R = 12x - 4 * 6 - 4 * (-3x)
R = 12x - 24 + 12x
R = 24x - 24
