The video tutorial explains how to solve systems of equations using the elimination method. It begins by introducing the concept of elimination, emphasizing the need to eliminate one variable by adding equations. The tutorial then discusses finding the least common multiple (LCM) to adjust coefficients, ensuring one is positive and the other negative for cancellation. The process of solving the equations is demonstrated, leading to the final solution. The tutorial concludes with a recap of the steps involved in using elimination to solve systems of equations.
