Question

3. Elige el procedimiento correcto para resolver la siguiente ecuación: (x-2)
A 3(x - 2) = -4(-x - 2)
3x - 6 = 4x + 8
3x - 4x = 8 + 6
-X = 14
(-1)(-x) = (-1)(14)
X = -14
B 3(x - 2) = -4(-x + 2)
3x - 6 = 4x - 8
3x - 4x = -8 + 6
-X=2
(-1)(-x) = (-1)(2)
x = -2

C 3(x - 2) = -4(-x + 2)
3x - 6 = 4x - 8
3x - 4x = -8 -6
-X = -14
(-1)(-x) = (-1)(-14)
X= 14
D 3(x - 2) = -4(-x + 2)
3x - 6 = 4x - 8
3x - 4x = -8 + 6
-X = -2
(-1)(-x) = (-1)(2)
X=2
