Question

3 (-(1-2 (1-x)))=-2(x-2)

Answer 1

Respuesta:

3(-(1-2(1-x))) = -2(x-2)

3(-(-1(1-x))) = -2(x)-2(-2)

3(1(1-x)) = -2x-(-(2×2))

3(1-x) = -2x-(-4)

3-3x = -2x+4

3-4 = -2x+3x

-1 = x

x = -1

Verificación :

3(-(1-2(1-(-1))) = -2((-1)-2)

3(-(-1(1+1))) = -2(-3)

3(1(2)) = -(-(2×3))

3(2) = 1(2×3)

6 = 6

R// X vale -1
