# Lesson 3.3 SOLVING A ONE STEP VARIABLE EQUAtION

The student will be able to solve a one step variable equation

# OPENING

- x + 3 = 14 What does x represent? How did you figure it out?
- y/12 = 3 What does y represent? How did you figure it out?

# LESSON

**Equations**: a full number sentence; it must be balanced (like a see-saw).

**Solving for x**= finding what x is going to be

**Inverse Operations=** operations that undo each other

- subtraction & addition are inverse operations of each other
- multiplication & division are inverse operations of each other
