y=-8-4\left(-4\right)-7\left(-4\right)+6
Consider the second equation. Insert the known values of variables into the equation.
y=-8+16+28+6
Do the multiplications.
y=8+28+6
Add -8 and 16 to get 8.
y=36+6
Add 8 and 28 to get 36.
y=42
Add 36 and 6 to get 42.
z=42
Consider the third equation. Insert the known values of variables into the equation.
x=-4 y=42 z=42
The system is now solved.
