x%2By=14
x=14-y Use this to substitute for x.
x%5E2%2By%5E2=196 Substitute for x.
%2814-y%29%5E2%2By%5E2=196
-y%5E2-28y%2B196%2By%5E2=196 Subtract 196 from each side.
-28y=0 Divide each side by -28
y=0
x=14-y=14-0=14
ANSWER: The solution is (14,0)

CHECK:
x%5E2%2By%5E2=196
14%5E2%2B0%5E2=196
196=196
