Convert linear equations in various forms into standard form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. This resource explains this method by showing an example along with a video.

This Purplemath lesson describes how to solve a system of linear inequalities by graphing.
