Solving One Step Equations: Addition and Subtraction

This video tutorial covers solving one-step equations using addition and subtraction. It explains the concept of equations as balance scales, where operations on one side must be mirrored on the other. The tutorial introduces inverse operations, which are used to solve equations by undoing the operation performed on the variable. Examples are provided for both addition and subtraction scenarios, and viewers are encouraged to practice with given problems. The video concludes with a summary of key points and additional practice problems.

What is the main idea behind an equation being like a balance scale?

• Both sides must have the same constants.

• Both sides must have the same operations.

• Both sides must be equal in value.

• Both sides must have the same number of variables.
