6. I’ M THINKING OF A N UMBER ….. If you multiply it by 3 and add 2, the result is 8 * To solve the problem, you can use the “work backwards strategy”. Undo each operation in reverse order.

8. 2 X + 2 = 12

9. 9 = 4 + 5 X

11. 4 X + 3 = -9

12. 3 X – 3 = 6

13. W ITH Y OUR P ARTNER Solve the following equations on a sheet of paper using Algebra Tiles. For each problem: (1) Write the equation (2) Draw a picture of what you did (3) Write the solution #1. 3x + 6 = 15 #2. -6 = 2x + 4 #3. 2x + -1 = 7 #4. -3x + 1 = -8

14. A F EW N OTES ….. A 2 step equation contains 2 operations. To solve a 2 step equation, use inverse operations to undo each in reverse order of the order of operations.
