Answer 1

Respuesta:

-2x+8y+10z=0

$-2x+8y+10z=0\\-2x+8y+10z-\left(8y+10z\right)=0-\left(8y+10z\right)\\-2x=-\left(8y+10z\right)\\\\\frac{-2x}{-2}=\frac{-\left(8y+10z\right)}{-2}\\\\x=4y+5z$

+3x+5y+1z=0

$+3x+5y+1z=0\\3x+5y+z=0\\3x+5y+z-\left(5y+z\right)=0-\left(5y+z\right)\\3x=-\left(5y+z\right)\\\\\frac{3x}{3}=\frac{-\left(5y+z\right)}{3}\\\\x=-\frac{5y+z}{3}$
