conversations.value: A football team has 105 members.  There are twice as many players on the offense as there is on the defense. There is half the number of players on the special teams as there is on the defense.  How many players are on the defense?
  Give me a clear explanation.

conversations.value: Let x represent the number of players on the defense
  Offense:2x
  Special Teams:(1/2)x
  Total:x+2x+(1/2)x=105
  (7/2)x=105
  x=105(2/7)=30 players
