  1. -4x > -16...divide by -4 and change inequality sign
         x < -16/-4
         x < 4

    2. -y/2 < 6 ...multiply both sides by 2
         -y < 12 ...multiply both sides by -1 and change inequality sign
          y > -12

    3. -5a < -20....divide both sides by -5 and change inequality sign
         a > -20/-5
         a > 4

    4. -b/2 > -1....multiply both sides by 2
         -b > -2...multiply both sides by -1 and change inequality sign
         b < 2

    5. -4b < 24....divide both sides by -4 and change inequality sign
         b > -24/4
        b > - 6

    6. -7c < -14....divide both sides by -7 and change inequality sign
         c > -14/-7
         c > 2

    7. -d/3 > -9...multiply both sides by 3
        -d > -27...multiply both sides by -1 and change inequality sign
         d < 27
