y=\left(2+1\right)\times 2^{2}
Consider the second equation. Insert the known values of variables into the equation.
y=3\times 2^{2}
Add 2 and 1 to get 3.
y=3\times 4
Calculate 2 to the power of 2 and get 4.
y=12
Multiply 3 and 4 to get 12.
z=12
Consider the third equation. Insert the known values of variables into the equation.
x=2 y=12 z=12
The system is now solved.
