y=-\left(-3\right)-6\left(-3\right)-8
Consider the second equation. Insert the known values of variables into the equation.
y=3-6\left(-3\right)-8
The opposite of -3 is 3.
y=3+18-8
Multiply -6 and -3 to get 18.
y=21-8
Add 3 and 18 to get 21.
y=13
Subtract 8 from 21 to get 13.
z=13
Consider the third equation. Insert the known values of variables into the equation.
x=-3 y=13 z=13
The system is now solved.
