Solving two step equations with a decimal

The video tutorial explains how to use inverse operations to solve equations. It focuses on isolating the variable by undoing operations applied to it. The example equation X / 7 - 0.5 = 2.5 is solved by first adding 0.5 to both sides using the addition property of equality, and then multiplying both sides by 7 to isolate X. The tutorial concludes with a review and addresses questions from the audience.

Explain how the division of X by 7 is undone in the equation.

What is the final value of X after applying all inverse operations in the equation?
