1. Step 1: Simplify Both Sides, if possible Distribute Combine like terms Step 2: Move the variable to one side Add or Subtract Like Term Step 3: Solve for the variable Use opposite operations to cancel numbers Math I: Unit 1 Steps to Solving Equations with Variables on Both Sides Example Problem:

2. Ex 1 Ex 4 Ex 3 Ex 2

3. Types of Solutions ONE Solution NO Solution MANY Solutions There is only one answer that makes the equation true (EX: x=3 This is the answer) There is no number that will satisfies both sides of the equation. Variables will cancel and a false statement is left. (EX: 5=3 Answer: No solution) Any number substituted for the variable will make the equation true. All variables will cancel and a true statement will be left. (EX: -2=-2 Answer: All real numbers)

4. Practice: Solve each equation. #1 # 4 # 3 # 2
