Dear ms excel user/programmers:

I hope this question is not repeated before. But anyway

highly appreciate anyone can tell me how (or hint) to use ms excell
and/or visual c/c++, basic, or octave(emulate matlab) to solve:
(12-x)^2 + y^2 =15^2,
(16+y)^2+x^2=25^2

(by programming or using its built in function)?

that ^2 mean square.

looking to any excel user, mathmatician, and/or programmer's help,
eric, [email protected]
