Solving One-Step Equations

There are many effective solution pathways for a system of two linear equations. They are all similar in that they involve 4 main steps. 1) use the equations in two variables to create a new equation in only one variable, 2) solve the new equation, 3) substitute that variable’s solution value into one of the original equations in the system of equations, and 4) solve that equation for the other variable. ................
