1. Let Me See You 1-2 Step Two-Step Algebraic Equations

2. Today’s Vocabulary Two-Step Equations Coefficient Constant

3. Two Step Equations Two-Step Equations are equations that require two-steps to solve.  You will ADD or SUBTRACT and then MULTIPLY or DIVIDE. 3x + 8 = 29

4. Coefficient Coefficient – The number that is attached to a variable 3x + 8 = 29 Coefficient

5. Coefficient To get rid of the coefficient, you will either MULTIPY or DIVIDE

6. Constant The constant is the number that is not attached to a variable.  It MUST be on the same side of the equal sign as the variable. 3x + 8 = 29 Coefficient Constant

7. Constant To get rid of the constant, you will either ADD or SUBTRACT You get rid of the constant FIRST!!

8. 4x + 12 = 20

9. 6x + 3 = 154 -17x + 2 = -8 5x + 15 = 24 -7x - 11 = 33 4x - 13 = -63 -8x + -12 = -20 Label the Coefficient and the Constant

10. How do I solve two-step equations? To solve two-step equations, you do order of operations in REVERSE  This means that you do addition or subtraction FIRST

11. Reverse order of operations? What does that mean? Isn’t there an easier way to understand this?

12. How do I solve two-step equations? To solve two-step equations, you get rid of the constant FIRST  This means that you do addition or subtraction FIRST

13. 4x + 12 = 28 Two-Step Equations Which number do I “get rid of” first? What operation do I do? What number do I “get rid of” next? What operation do I do?

14. 3x - 5 = 7 Two-Step Equations Which number do I “get rid of” first? What operation do I do? What number do I “get rid of” next? What operation do I do?

15. 6x + 12 = 24 Two-Step Equations Which number do I “get rid of” first? What operation do I do? What number do I “get rid of” next? What operation do I do?

16. -2x - 4 = 10 Two-Step Equations What number do I “get rid of” next? What operation do I do?

17. 2x + 4 = -10 Two-Step Equations Which number do I “get rid of” first? What operation do I do? What number do I “get rid of” next? What operation do I do?

18. -5x + 12 = 32 Two-Step Equations What operation do I do? What number do I “get rid of” next? What operation do I do?

19. -3x + 6 = 27 Two-Step Equations Which number do I “get rid of” first? What operation do I do? What number do I “get rid of” next? What operation do I do?

20. -9x + 9 = -18 Two-Step Equations What operation do I do? What number do I “get rid of” next? What operation do I do?

21. 6x + 12 = 18 Two-Step Equations

22. 5x - 15 = 20 Two-Step Equations

23. -8x + 10 = 42 Two-Step Equations

24. -15x - 5 = 40 Two-Step Equations
