Question

(x-y)+{x-3[z+y-(x+2y+z)-4(x+2]}

Answer 1

Respuesta:

$\left(x-y\right)+\left(x-3\left(z+y-\left(x+2y+z\right)-4\left(x+2\right)\right)\right)$

simplificamos

$=x-y+x-3\left(z+y-\left(x+2y+z\right)-4\left(x+2\right)\right)$

Agrupar términos semejantes

$=-3\left(z+y-\left(x+2y+z\right)-4\left(x+2\right)\right)+x+x-y$

Sumar elmentos similares

$=-3\left(z+y-\left(x+2y+z\right)-4\left(x+2\right)\right)+2x-y$

$=-3\left(-5x-y-8\right)+2x-y$

$=15x+3y+24+2x-y$

$=17x+2y+24$
