Learn how to use substitution to solve systems of linear equations with one or more variables. Follow the five-step process with examples, explanations and practice problems.
method for solving systems of equations, called the substitution method. Example 1. Note that the second equation in this system of equations is of the form “y = something”, and this “something” only involves the variable x. {5x − 2y = 16 y = −2x + 1 This means we can replace y in the first equation by the expression that y equals

Systems of Equations - Substitution Objective: Solve systems of equations using substitution. When solving a system by graphing has several limitations. First, it requires the graph to be perfectly drawn, if the lines are not straight we may arrive at the wrong answer. Second, graphing is not a great method to use if the answer is
equations within the system of equations. We can solve a system of equations by substitution, by elimination, or graphically. We will look at the substitution method in this section . Substitution Method. In the substitution method, we start with one equation in the system and solve for one variable in terms of the other variable.

Note: There are two Solving Systems of Linear Equations handouts, one by Substitution and another by Elimination. A linear equation is an equation for a line. A system of equations involves one or more equations working together. This handout focuses on systems of equations with one solution for the system. These systems are known as ...
210 Chapter 5 Systems of Linear Equations 5.2 Lesson Lesson Tutorials Another way to solve systems of linear equations is to use substitution. EXAMPLE 1 Solving a System of Linear Equations by Substitution Solve the system by substitution. y = 2x − 4 Equation 1 7x − 2y = 5 Equation 2 Step 1: Equation 1 is already solved for y. Step 2: Substitute 2x − 4 for y in Equation 2.
In this method you will take one equation and solve for either x or y. Then you will substitute this into the other equation. EXAMPLE: Solve the system using the substitution method: 2 5 16 3 11 − + =− − = x y x y. You can solve for any variable in any equation to begin this problem. You want to choose the variable that will
