2=x
Consider the first equation. Add 1 and 1 to get 2.
x=2
Swap sides so that all variable terms are on the left hand side.
2=y
Consider the second equation. Insert the known values of variables into the equation.
y=2
Swap sides so that all variable terms are on the left hand side.
z=2^{2}
Consider the third equation. Insert the known values of variables into the equation.
z=4
Calculate 2 to the power of 2 and get 4.
x=2 y=2 z=4
The system is now solved.
