1. Solving 2-step equations Day 1, lesson 2.2 Objective: solve for the unknown Solution: A number that makes the equation true.

2. x + 7 = 10 - 7 -7 x = 3 P E M A D S

3. 11c + 7 = 51 - 7 -7 11c = 44 11 c = 4 P E M A D S

4. 3 = 3n + 9 - 9 -9 -6 = 3n 3 3 -2 = n P E M A D S

5. 6x + 14 = -40 -14 -14 6x = -54 6 6 x = -9 P E M A D S

6. x - 5 = 4 3 ___+ 5 + 5 x = 9 3 3 3 ( ) x = 27 P E M A D S

7. 6 + x = 4 5 -6 -6 x = -2 5 5 5 ( ) x = -10 P E M A D S

8. 11x + 5x = 48 16x = 48 16 x = 3 P E M A D S

9. You are making a bulletin board to advertise community service opportunities in your town. You plan to use half a sheet of construction paper for each ad. You need 5 sheets of construction paper for a title banner. You have 18 sheets of construction paper. How many ads can you make? Using an equation as a model knowneedplan -paper per ad: ½ sheet -paper per banner: 5 sheets -total paper: 18 sheets The number of ads you can make. Write and solve an equation. Let the variable represent the unknown. You are making a bulletin board to advertise community service opportunities in your town. You plan to use half a sheet of construction paper for each ad.
