As the name implies, a system of equations is indeed a system that involves 2 or more equations in it. The system of equations involves solving 2 linear equations simultaneously. This means that your equations will most probably have two variables; one, x-variable, and second, y-variable. There are several methods to solve systems of equations ... This page will show you how to solve two equations with two unknowns. There are many ways of doing this, but this page used the method of substitution. Note the "=" signs are already put in for you.Systems of Equations Introduction. Linear Systems with Three Variables. Chapters. Solving Equations and Inequalities. Solutions and Solution Sets.
