# Math Quiz: Systems Of Equations!

8 Questions | Total Attempts: 52  Settings  Are you ready for a maths quiz about the systems of equations? A system of equation is formed when one has two equations with the same set of the unknown, and a student is expected to find the unknown. One can use three ways to solve linear equations in two variables graphing, substitution method, or elimination method. Do take up the quiz and get to see how well you will use these methods to solve the equations below.
