Answer 1

3. 2x + 1 = 17
      2x    = 16
         x   = 8

4. 3x - 5 = 22
       3x   = 27
         x   = 9

5. 23 = 3p - 1
    3p = 24
      p = 8

6. 3/5 x = 12
      x   = 12 x 5 / 3
      x  = 20

7. 3x + 7 = x - 17
        2x   = -24
          x  = -12

8. 5x < 20
     x < 4
Hp = {0,1,2,3}

9. 12 - 2x > x - 3
     - 3 x   > -15
          x   < 5

Hp = {1,2,3,4}
