Show that for any epsilon in:

|2x + 3y - 5| < epsilon

There is a delta value:

sqrt((x - 1)^2 + (y - 1)^2) < delta

Solve for delta in terms of epsilon

------

I understand that this is a proof that the limit of f(x,y) as (x,y) -> (1,1) is 5.

But I'm stuck solving for delta in terms of epsilon.

thanks!
