The video tutorial explains how to solve a system of equations using the elimination method. It begins by introducing the concept and discussing why elimination is used when coefficients are not equal to one. The instructor then demonstrates how to eliminate fractions by finding a common multiple and multiplying through the equations. The process of adding or subtracting equations to eliminate variables is shown, and the solution is found by substituting back into the equations. The tutorial emphasizes the preference for adding negative numbers over subtracting to simplify the process for students.
