y=-2\times 3^{2}
Consider the second equation. Insert the known values of variables into the equation.
y=-2\times 9
Calculate 3 to the power of 2 and get 9.
y=-18
Multiply -2 and 9 to get -18.
z=-18
Consider the third equation. Insert the known values of variables into the equation.
x=3 y=-18 z=-18
The system is now solved.
