10. Only One Number Works All numbers can work. No possible number can work. 4x = 2x + 61x + 10 = 1x + 201x + 4 = 1x + 4 -2x 2x = 6 x = 3 Only one possible answer -1x 10 = 20 -1x 4 = 4 *All variables are eliminated *All variables are eliminated No Solution, the scale is not balanced. Infinite Solutions, the scale is balanced with any x. 6 10 20 44 3 3

11. 1. 4 – 2(x - 7) = -2x + 18 2. 5(x – 3) – 3x = -16 + 2x 3. -m + 8 = 8(1 – 5m) - 4m4. -7x + 7 = -6x + 3(5x - 3) Solve:

12. Solve Equations like… - 2(6 – 3m) = - 17 + 6m Let’s go back to our “I can” statement and solve it with our new skills.
