Solving Two-Step Equations with Decimals

This video tutorial teaches how to solve two-step equations with decimals. It begins by identifying the values attached to the variable through multiplication and addition. The tutorial then demonstrates how to eliminate the addition by adding the inverse, followed by solving for the variable using division. The solution is verified by substituting the value back into the original equation. The video concludes with encouragement to practice more and check out additional resources.
