x + 1 / 3 - x / 2 = x - (x + 4) / 6
Multiplicamos la igualdad por el mcm de (2,3,6) = 6 6x + 2 - 3x = 6x - x - 4 6x + 2 - 3x = 5x - 4 3x + 2 = 5x - 4 3x - 5x = - 4 - 2 - 2x = - 6 x = - 6 / -2 x = 3

6x + 2 - 3x = 6x - (x+4)
3x + 2 = 6x - x - 4
3x -6x + x = -4 -2
-2x = -6 /•-1
2x = 6 /:2x
x = 3.
El valor de x = 3. Espero que se entienda :) saludos.
