1. Solve Multi-Step Equations like… 2x −5(x + 6) = 34 + 5x Which of the following are like terms? 3x 7y -2xy 3y 10xy -3x 7yx Write down this problem on your READY RECALL SHEET Be prepared to explain your answer if you are called on. Page 14 of your INB

2. Unit 1: Linear Equations This chapter will include some review from last year. Mostly, we will be solving equations – lots of equations! 1.4 – Muli-Step Equations

3. Get into your 4-Square Groups Solve Multi-Step Equations like… 2x −5(x + 6) = 34 + 5x Page 14-15 of your INB tape

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

5. LET’S SOLVE A MULTI-STEP EQUATION!

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

8. - 2x -18 = 8x - 6 + 6 -12 = 8x = x -3 2 Step 1: Simplify Both Sides Step 1: Simplify Both Sides Step 2: Move Variable to One Side Step 2: Move Variable to One Side + 6 Step 3: Isolate the Variable Term Step 3: Isolate the Variable Term Step 4: Isolate the Variable Step 4: Isolate the Variable 88

9. 1. 18x -4 = 3x + 1 2. 20x + 3 = -10x + 9 3. -2n -5n -6 = 2n – 3n4. 1 + 5a = 9 + a +2 + 2

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

11. 1. 2x + 12 + x = 3(2x – 4) 2. 4(7 + m) = 13 + m 3. -8(5 – 3n) = 40 + 8n4. 3(4x + 4) – 7x = -23 -2x

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