system%28L=2A%2B10%2CN=3L-40%2CA=A%29

Average Age:
%28L%2BN%2BA%29%2F3
%28%282A%2B10%29%2BN%2BA%29%2F3
%282A%2B10%2B%283L-40%29%2BA%29%2F3
%282A%2B10%2B%283%282A%2B10%29-40%29%2BA%29%2F3
%282A%2B10%2B6A%2B30-40%2BA%29%2F3
%289A%2B10%2B30-40%29%2F3
9A%2F3

Average Age is 9A%2F3=highlight%28highlight%283A%29%29.
That is all you can do. You have three unknown variables but just two linear equations.
