1. SOLVING MULTI-STEP EQUATIONS By Ms. Morgan

2. Students will be able to: Calculate the missing angle measurements when given two parallel lines cut by a transversal. Solving multi-step equations by combining like terms, using the distributive property or moving variables to one side of the equation.

3. Math Standard: 8.G.5 Calculate the missing angle measurements when given two parallel lines cut by a transversal. 7.A.4 Solving multi-step equations by combining like terms, using the distributive property or moving variables to one side of the equation.

4. Do now: What is the inverse (opposite) operation of Addition Subtraction Multiplication Division

5. New Concept Solving equations by moving variables to one side Step 1: Draw the line over the equal sign Step 2: Move all the variables to one side and all the numbers to the other by using the inverse operation. Step 3: Combine like terms Step 4: Simplify

6. Equation: 9n + 36 = 54 Step 1: Draw the line over the equal sign Step 2: Move all the variables to one side and all the numbers to the other by using the inverse operation. Step 3: Combine like terms Step 4: Simplify

7. Equation: 3b + 2b – 10 = 50 Step 1: Draw the line over the equal sign Step 2: Move all the variables to one side and all the numbers to the other by using the inverse operation. Step 3: Combine like terms Step 4: Simplify

8. Equation: 5n + 20 = 36 + n Step 1: Draw the line over the equal sign Step 2: Move all the variables to one side and all the numbers to the other by using the inverse operation. Step 3: Combine like terms Step 4: Simplify

9. On your own: USE LOOSE LEAF PAPER FOR THESE PROBLEMS. THEY WILL BE COLLECTED AND GRADED. PLEASE BE NEAT! SOLVE THE FOLLOWING EQUATIONS. SHOW ALL YOUR WORK -15 + c = 755m – 2 = 33 12n + 12 = 1446n + 2 = 3n + 11 b/6 + 20 = 25 h / 3 = 5 + 3 4b + 5b – 2b = 49r + 2r = 9 6v – 4v + 57 = 87 5m + 20 = 2m + 44 Step 1: Draw the line over the equal sign Step 2: Move all the variables to one side and all the numbers to the other by using the inverse operation. Step 3: Combine like terms Step 4: Simplify
