Solve a System with a Quadratic Equation A system of equations is a set of two or more equations that use the same variables. A solution of a system of equations is the set of values for the variables that makes ALL the equations true. On a graph: the solutions of a system is any point (x, y) where ALL the graphs of the functions in the system intersect. Solutions
