Linear Equations: Solutions Using Substitution with Two Variables To solve systems using substitution, follow this procedure:     Select one equation and solve it for one of its variables.      In the other equation, substitute for the variable just solved.      Solve the new equation.      Substitute the value found into any equation involving both variables and solve for the

Unformatted text preview: other variable. • Check the solution in both original equations. Usually, when using the substitution method, one equation and one of the variables leads to a quick solution more readily than the other. That's illustrated by the selection of x and the second equation in the following example....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
