2^{2}+3^{4}=A
Consider the third equation. Insert the known values of variables into the equation.
4+3^{4}=A
Calculate 2 to the power of 2 and get 4.
4+81=A
Calculate 3 to the power of 4 and get 81.
85=A
Add 4 and 81 to get 85.
A=85
Swap sides so that all variable terms are on the left hand side.
P=2 Q=3 A=85
The system is now solved.
