Last time we solved One-Step and Two-Step Equations. What do you think a Multi-Step Equation is?

LET’S SOLVE A MULTI-STEP EQUATION!

Multi-Step Equation Step 1: Simplify Both Sides Step 2: Move Variable to One Side Step 3: Isolate the Variable Term Step 4: • Isolate the Variable

INTERACTIVE NOTEBOOK TIME

Step 1: Simplify Both Sides -2x -2x Step 2: Move Variable to One Side • -18 = 8x - 6 Step 3: Isolate the Variable Term + 6 + 6 • -12 = 8x 8 8 Step 4: • Isolate the Variable • -3 • 2 • = x

You Try it! 2. 20x + 3 = -10x + 9 1. 18x -4 = 3x + 1 3. -2n -5n -6 = 2n – 3n 4. 1 + 5a = 9 + a +2 + 2

Step 1: Simplify Both Sides 10x – 5 – 7x = - 48 - 40x - 48 - 40x 3x - 5 = Step 2: Move Variable to One Side +40x +40x 43x - 5 = - 48 Step 3: Isolate the Variable Term +5 +5 43x = -43 43 43 Step 4: • Isolate the Variable x = -1

You Try it! 2. 4(7 + m) = 13 + m 1. 2x + 12 + x = 3(2x – 4) 3. -8(5 – 3n) = 40 + 8n 4. 3(4x + 4) – 7x = -23 -2x

Let’s go back to our “I can” statement and solve it with our new skills. Solve Multi-Step Equations like… 2x −5(x + 6) = 34 + 5x
