can be calculated via:

Answer:
y=-1/4x-4
Step-by-step explanation:
Answer:
x= -2
y=0
z= 1
Step-by-step explanation:
{-x+5y-10z=-8
2x-y+10z=6}
{2x-y+10z=6
-7x-3y-10y=4}
{-x+5y-10z=-8
2x-y+10z=6} = x+4y=-2
{2x-y+10z=6
-7x-3y-10y=4} = -5x-4y=10
{x+4y=-2
-5x-4y=-10}. =. y= 0 x= -2
substitute x and y in -x+5y-10z=-8
-(-2)+5(0)-10z=-8
solve for z
z= 1
(x,y,z) = (-2,0,1)
hope this helps
absolute value means always positive
