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.

What is the method called that involves adding or subtracting equations to eliminate one of the variables?

How do you determine the common multiple of two numbers, such as four and three?

What is the importance of making one of the equations negative when adding them together?

After finding the value of X, how do you proceed to find the value of Y?

What is the final coordinate point obtained from the equations discussed?
