Combining Like Terms in Linear Equations

The video tutorial explains how to solve a multi-step equation by first combining like terms on both sides of the equation. It then demonstrates how to collect variable terms using inverse operations and isolate the variable to find the solution. The solution is verified by substituting the value back into the original equation. The tutorial concludes with a summary of the steps and a closing remark.
