Using Elimination and Adding to Solve a System of Equations

The video tutorial explains how to solve a system of equations using the elimination method. It begins by introducing the concept of elimination and the importance of having the same coefficients for variables. The teacher demonstrates how to use elimination by addition when coefficients have opposite signs. The process involves aligning equations, adding them to eliminate a variable, and solving for the remaining variable. Finally, the value of the solved variable is substituted back into one of the original equations to find the value of the other variable.
