RE: Solve for X and Y
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:

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

RE: Solve for X and Y
You could use a graphical approach, using the Advanced Graphing App. The two solutions show up nicely at the intersections of the two expressions:

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