DioPhantine is A * * 2 + b * * 2 = c * * 2
but this seems like A * x + B * x = C where x > 0 || y > 0
am i wrong to argue you on this?
A Diophantine equation is simply one in which we are only interested in integer solutions. This is known as a linear Diophantine equation.
so a linear equation is part of the set of Diophatine equations. Thanks! I didn't quite get that at first.
The important part is that we're only interested in integer ("whole number") solutions. In this case, the Diophantine equation is
n = 5x + 3y
and we only care about cases where x and y are both integers. For example, if n were 11, we don't care about the solution x=1.6, y=1. We're only interested in the solutions like x=1, y=2.
