1. Section 4-4

3. 1. Objective: Solve two-step equations.

4. 2. Two-step equations have two different operations.

5. 3. To solve two-step equations, “undo” the operations in reverse order of the order of operations.

6. 3x + 2 = 23 -2y -7 = 3

7. X = 3 3x + 1 = 10

8. m = -4 6m + 1 = -23

9. S = -4 -8s + 1 = 33

10. d = 8 5 + 4d = 37

11. t = 5 2 = 3t -13

12. f = 0 4 = 4 + 7f

13. X = 3 5x + 4 = 19
