SOLVING MULTI-STEP EQUATIONS By Ms. Morgan

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.

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.

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

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

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

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

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

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 c = 755m – 2 = 33 12n + 12 = 1446n + 2 = 3n + 11 b/ = 25 h / 3 = b + 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
