Solving Systems of Equations by Substitution

Systems of equations are used to find the point where two or more lines intersect. One way to solve these equations is to graph the lines on the same coordinate grid and find the name of the point where the lines intersect. An easier, and usually faster, way to do this is to use substitution. Be sure to read Lesson 7.2 before completing the homework.
