WebThe method of substitution can be used to solve systems of linear equations by solving an equation for one variable and then substituting the resulting expression for that variable … WebSolve a system of equations by substitution. Step 1. Solve one of the equations for either variable. Step 2. Substitute the expression from Step 1 into the other equation. Step 3. Solve the resulting equation. Step 4. Substitute the solution in Step 3 into one of the original equations to find the other variable. Step 5.
WebIn a previous lesson, students solved systems of linear equations by graphing. Here, they transition to solving systems algebraically—by substitution—and to reasoning about systems without a context. The lesson activates and builds on what students have learned in grade 8 about solving by substitution. Students see that a system can be ...
