x=4
Consider the first equation. Swap sides so that all variable terms are on the left hand side.
y=4^{2}-4\times 4+8
Consider the second equation. Insert the known values of variables into the equation.
y=16-4\times 4+8
Calculate 4 to the power of 2 and get 16.
y=16-16+8
Multiply -4 and 4 to get -16.
y=8
Subtract 16 from 16 to get 0.
x=4 y=8
The system is now solved.
