Solving Simultaneous Equations

This video introduces the concept of solving simultaneous equations algebraically. It explains the need for multiple equations when dealing with multiple variables, such as two variables requiring two equations. The video also touches on scenarios with more than two variables, requiring an equal number of equations to solve. It concludes with an introduction to two methods for solving these equations: substitution and elimination.
