In a system of equations in three variables, you can have one or more equations, each of which may contain one or more of the three variables, usually x, y, and z.The introduction of the variable z means that the graphed functions now represent planes, rather than lines. Or click the example. Systems Solver. Key Takeaways Key Points. No matter whether you want to solve an equation with a single unknown, a system of two equations of two unknowns, the system of three equations and three unknowns or linear system with twenty unknowns.
