Answer 1

you can pretty much eye-ball the answer out

look, 25 is 5^2, does this reminds you of the familiar 3^2+4^2=5^2?

Answer 3

does x=3 and y=4 make the second equatio true?

Answer 4

Yes

Answer 5

good, now you have your answer without even sovling the equations

Answer 6

Okay, thanks!

Answer 7

But isn't there another answer?

Answer 8

Oh yeah, you're right. If it's a circle there has to be another answer too.
