Solving a system of equations with infinite many solutions

The video tutorial covers solving systems of equations using the elimination method. It begins with setting up the problem and discussing the differences between substitution and elimination methods. The teacher emphasizes aligning variables and adjusting coefficients to find common multiples. The process of multiplying equations to eliminate variables is demonstrated, leading to the solution of the system.

How do you determine a common number for the variables in the equations?

What is the smallest number that both 2 and 10 divide into, according to the discussion?
