1. Equations, Equations, Equations 3102.3.11 Solve multi-step linear equations with one variable.

2. Solving Equations by Adding and Subtracting x – 8 = 17 + 8 = +8 x = 25

3. What happens when two signs are beside each other?? x + (-3) = -9 Do Leave, Change, Opposite x - 3 = -9 The changes are in red! Now SOLVE!! + 3 = +3 Do the opposite & Add 3 to both sides! x = -6

4. Try this one!! y – ( -8) = 15 y + 8 = 15 - 8 - 8 y = 7

5. Solving Equations Using Multiplication and Division -5x = 25 -5 -5 x = -5

6. Try a Division Problem 1 x = 54

7. Solving Two-Step Equations 5x + 2 = 27 - 2 = -2 5x = 25 5 5 x = 5

8. Try this one!! 6x + 9 = 27 - 9 = -9 6x = 18 6 6 x = 3

9. Try this one! + 8 = + 8 x = 6 3 1 x = 18

10. Solving Equations with Variables on Both Sides 2x – 8 = x + 17 -x - x 1x - 8 = 17 + 8 = + 8 1x = 25 or x = 25

11. Try this one! 3(5x + 2) = 2(3x – 6) 15x + 6 = 6x - 12 -6x -6x 9x + 6 = - 12 - 6 = - 6 9x = - 18 9 9 x = -2
