What is a system of linear equations?

Back

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

How do you find the solution of a system of equations graphically?

Back

To find the solution graphically, plot each equation on the same graph. The point(s) where the lines intersect represent the solution(s) of the system.
