Solve Systems of Equations Using Substitution 🔍

To solve systems of equations by substitution simplify the equation to isolate one variable. It doesn't matter which one but let's use x. Next, substitute that equation into the variable x of the second equation and solve for the other variable, in this case y. Once you have y, just plug it in to either equation and solve for x.
