## Simultaneous Equations **What are Simultaneous Equations?** Simultaneous equations are a set of two or more equations with two or more unknown variables that must be solved together to find a unique solution that satisfies all equations. **Key Points** 1. You need as many equations as there are unknown variables to find a unique solution. 2. The **Elimination Method** involves adding or subtrac [Preview only]
