## Using the Substitution Method to Solve a System of Equations

The substitution method is most useful for systems of 2 equations in 2 unknowns. The main idea here is that we solve one of the equations for one of the unknowns, and then substitute the result into the other equation. We will solve second equation for y. Note: It does not matter which equation we choose first and homework help substation method second. Just choose the most convenient one first! Since the coefficient of y in equation 2 is -1, it is easiest to solve for y in equation 2.
