Solving a two step equation

The video tutorial explains how to solve a two-step equation involving a variable X. The instructor begins by introducing the equation and the goal of finding the value of X that makes the equation true. The process involves understanding the equation, undoing addition and subtraction, and then using multiplication to isolate the variable. The solution is verified by substituting the value back into the equation to ensure correctness.
