Solve a system of equations by multiplying one equation by a multiplier then adding them

The video tutorial explains how to solve systems of equations using the elimination method. It covers handling coefficients with the same or opposite signs, finding the smallest common multiple, and applying addition or subtraction to eliminate variables. The tutorial demonstrates solving a system of equations step-by-step, ensuring variables are aligned and coefficients are adjusted for elimination. The process concludes with finding the values of x and y.
