Systems of equations by using the solving technique x+3y=8, y=2x‐9

The video tutorial explains the substitution method for solving equations. It emphasizes the importance of identifying isolated variables and substituting their values into other equations. The tutorial demonstrates the process step-by-step, including applying the distributive property and solving for variables. Finally, it verifies the solution by plugging the values back into the original equations.
