### Abstract

Diophantine equations {*ax* + *by* = *c*; *a*, *b*, *c* ∈ ℤ} are classified according to parity constraints. Various types, so classified, are solved with the theory of integer structure, via the modular ring Z_{4}. The simplest forms are those where one of the variables is confined to a single class. However, the more complex equations have solutions that follow regular (*x*, *y*) class patterns. The famous Diophantine equation in Fermat’s Last Theorem is discussed in terms of the factor structure of the sum of two powers.
