Solving Equations:

1) 10x – 8 = -33 -2.5 2) 34 – 6x = -14 8

3) ⅔x + 15 = 33 27 4) - 23 - ⅝x = 7 -48

5) (x/7) + 40 = 43 21 6) 24 – (x/5) = 30 -30

7) (6x - 5) - (10x - 11) = 34 -7 8) 4(3x – 7) + 6(3x + 4) = -49 -1.5

9) 6(5x – 4) – 4(7x – 9) = 36 12 10) 6(4x – 5) - 5(7x - 6) = -110 10

11) 5(3x – 2) = 4(6x + 11) -6 12) 8(5x – 3) = 6(5x + 1) 3

13) 4(6x - 4) - 3 . = 7 x = 4 14) 4(3x + 3) . + 8 = -8 -9

11 6

15) 6(4x - 3) + 3 . = 15 x=5 16) 5(2x - 6) . - 15 = -10 9

7 12

17) 8(6x – 7) . + 40 = 72 x = 4.5 18) 2(8x - 5) + 2 . = -8 3

5 -5

19) 5(6x + 2) . + 3 = -22 x = -7 20) 7(5x + 4) + 22 . = -5 -3 9 11

Solving and Graphing Simple Inequalities:

1) 8x – 17 > -5 x > 1.5 2) 50 – ¾ x 68 x -24

3) 12x - 2 17x + 18 x < 4 4) 8(5x – 4) – 6(7x + 4) -64 x 4

5) 38 < 26 - ⅜ x x < -32 6) 6(4x -1) 7(4x - 2) x 2

7) 9(4x + 4) > 4(4x - 1) x > -2 8) -4 5(4x + 6) + 6(4x – 2) x - ½

Compound Inequalities:

1) 9x – 5 > -23 ∩ ¾ x + 5 8 2) 10x + 7 > 42 15 -9x 24

x > -2 ∩ x 4 x -2.5 x > -1

3) -26 7x + 2 < 23 4) 12 – 3x > 15 6x – 11 -35

x -4 ∩ x < 3 x < -1 x < -4

5) 14x - 5 -40 14 – 2x 10 6) 8x – 13 3 ∩ 16 - 6x 43

x < -2.5 x -2 x > 2 ∩ x < -4.5

7) 8 – 13x < 3 ∩ 16x - 31 -79 8) 25 – 6x > 43 -3x + 6 > 15

x > 0 ∩ x > -3 x < -3 x -3

Remember, all inequalities must be graphed.
