x+y=5

and x^x + y^y = 31

i have found x,y = 2,3 or 3,2

but i got the answer by merely substituting the values...

is there any proper way to find x and y??

- equations -
**Steve**, Thursday, May 23, 2013 at 11:37amthis equation is not easily to solve algebraically.

x^x + (5-x)^(5-x) = 31

can't take logs, or roots, or anything easy. Not sure what doing this kind of exercise is intended to teach.
