Question

a.
3x +{-[5y + 2(3x – 3) + 2-5(-x + 2y – 4(2-2))]-6(-2x + y)}​

Answer 1

Respuesta:

$26x-11y-4$

Explicación paso a paso:

$3x+\left(5y+2\left(3x-3\right)+2-5\left(-x+2y-4\left(2-2\right)\right)\right)-6\left(-2x+y\right)$

$3x+5y+2\left(3x-3\right)+2-5\left(-x+2y-4\left(2-2\right)\right)-6\left(-2x+y\right)$

$3x+5y+2\left(3x-3\right)+2-5\left(2y-x\right)-6\left(y-2x\right)$

$3x+5y+6x-6+2-5\left(2y-x\right)-6\left(-2x+y\right)$

$3x+5y+6x-6+2-10y+5x-6\left(-2x+y\right)$

$3x+5y+6x-6+2-10y+5x+12x-6y$

$26x-11y-4$
