K/2+9=30                         1. Start by getting rid of the number farthest from K
      -9   -9                          2. The nines cancel out, 30-9=21
K/2    = 21                         3. Next, get the 2 away from K 
/-2         /-2                        4. The 2 cancel out when divided, 21 divided by -2= -10.5  
K       = -10.5 
   K=-10.5
