How Do You Solve Systems Of Algebraic Equations Containing Two Variables?
• Make sure you have two equations with no exponents. Choose a method. There are three ways to solve a system like this: by graphing both lines, by adding the two equations together, or by substituting one equation into another. • Graphing is only an approximate method. Don’t use it unless you are specifically told to do so. You could graph your equations to check your work or understand what you’re doing. • The substitution method is fastest if one of the equations already has x or y by itself.
