Solving Simultaneous Equations: Elimination and Substitution Methods

The video tutorial covers solving simultaneous equations using two main methods: elimination and substitution. It explains how to handle linear equations by matching coefficients and eliminating variables, and how to rearrange equations for substitution. The tutorial also addresses solving quadratic equations by substitution, emphasizing the need to find multiple solutions for variables. Key techniques include multiplying equations, adding or subtracting to eliminate variables, and using factorization or the quadratic formula.

Explain the substitution method and when it is used.
