You can use the app Solve, then (in Symb) write the equations in E1 and E2; in Num give some guess tries for X and Y and press Solve:
X=9, Y=-4
Salvo
X=9, Y=-4

Not to forget the Linear Solver App, you simply enter your 6 numbers and push Solve.

Right, yes!

You could use a graphical approach, using the Advanced Graphing App. The two solutions show up nicely at the intersections of the two expressions:
Points (X,Y) = (4,9) and (9,-4)

and I was wrong two times, then, replying too soon
ok, the second equation is not linear...

solve({13*x+5*y=97,x^2+y^2=97},{x,y})
