Solving One Step Equations with Substitution

This video tutorial covers solving one-step equations using substitution. It includes three examples: determining the solution for P + 9.7 = 13.7, checking solutions for m + 4/5 = 2 4/5, and using the guess and check method to solve 4.5p = 36. The video emphasizes substituting values to verify solutions and encourages practice with provided problems.

What is the main topic of this lesson?
