2(4x + 5 - 2 - 3x) + 4( - 2 + 2x + 4 - x) = 2 - x(3 + 2)?

2(4x + 5 - 2 - 3x) + 4( - 2 + 2x + 4 - x) = 2 - x(3 + 2).

En resumen

2(4x + 5 - 2 - 3x) + 4( - 2 + 2x + 4 - x) = 2 - x(3 + 2) = 2(x + 3) + 4(2 + x) = 2 - x(5) = 2x + 3 + 8 + 4x = 2 - 5x = 11 + 6x = 2 - 5x 6x + 5x = 2 - 11 11x = - 11 x = - 11 / 11 x = - 1.

2(4x + 5 - 2 - 3x) + 4( - 2 + 2x + 4 - x) = 2 - x(3 + 2) =

2(x + 3) + 4(2 + x) = 2 - x(5) =

2x + 3 + 8 + 4x = 2 - 5x =

11 + 6x = 2 - 5x

6x + 5x = 2 - 11

11x = - 11

x = - 11 / 11

x = - 1.
