What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect on a graph.

How can you determine the number of solutions in a system of equations?

Back

The number of solutions can be determined by graphing the equations: 1 solution (intersecting lines), no solution (parallel lines), or infinitely many solutions (same line).

What is a system of inequalities?

Back

A system of inequalities consists of two or more inequalities that involve the same variables. The solution is the region where the inequalities overlap on a graph.
