2\left(-2\right)-y=4
Consider the second equation. Insert the known values of variables into the equation.
-4-y=4
Multiply 2 and -2 to get -4.
-y=4+4
Add 4 to both sides.
-y=8
Add 4 and 4 to get 8.
y=-8
Divide both sides by -1.
-2-\left(-8\right)+6z=0
Consider the third equation. Insert the known values of variables into the equation.
-2+8+6z=0
Multiply -1 and -8 to get 8.
6+6z=0
Add -2 and 8 to get 6.
6z=-6
Subtract 6 from both sides. Anything subtracted from zero gives its negation.
z=\frac{-6}{6}
Divide both sides by 6.
z=-1
Divide -6 by 6 to get -1.
x=-2 y=-8 z=-1
The system is now solved.
