I am trying to solve

5

^{2x-y}=625

2

^{x-y}=32

I have tried solving using the 2d template and the solve( function and i am getting the solution returned:

{5

^{2x-y}=625,2

^{x-y}=32}

When I transform into two linear equations: 2x - y = 4 and x - y = 5, i get the correct result.

this is more an exercise for me in learning the classpad than an actual math problem, so if anybody knows how i can use the calc to solve this, (or tell me it cant be done) then i would be very grateful.
