Substitution Method | Algebra | Chegg Tutors

One way to solve systems of equations is by substitution. In this method, solve an equation for one variable, then substitute that solution in the other equation, and solve. Use substitution as a method for solving a system of equations when the number of equations and variables is equal (if two variables, there must be two equations; three variables, three equations, etc.) and one of the equations can easily be solved for one variable. If there is no solution to the system of equations (parallel lines), the substitution method will result in something nonsensical, such as 4 = -2. One of the strengths of the substitution method is that it works for systems of equations that are difficult or impossible to graph.
