Solving a System of Equations Using Elimination and Multipliers

The video tutorial covers solving systems of equations using the elimination method. It begins by discussing why substitution might not be ideal when no variable has a coefficient of 1. The teacher then explains the elimination method, which involves adding or subtracting equations to eliminate a variable. The process of finding common multiples is detailed, followed by solving the equations to find the values of X and Y. The tutorial concludes with an example to reinforce the learning.
