Systems of Equations or Inequalities Solver

This algebra solver enables you to solve or graph systems of equations or inequalities. Here are some hints on the calculator usage:
  • the equation system solver can solve systems of linear equations only.The default number of equations (or inequalities) is 2, but you can specify more, if needed.
  • a system of inequalities can only be solved by graphing. Inequalities don't have to be linear; however only two variables (and up to 9 inequalities) are allowed. The intersecting area on the graph represents the solution.
  • you can use the Inequalities tab to graph equations as well.
  • hover the mouse over the question marks for more detailed help.
  • if any solution steps are unclear, click on the step to see an explanation. Note that (while graphing) 'solution steps' refer to converting inequalities to the standard (explicit) form. These steps can be found below the graph.
