How did the U. S. Navy and Air Force work together during the Cuban missile crisis?

In the fall of 1962, the United States and the Soviet Union came as close as they ever would to global nuclear war. Hoping to correct what he saw as a strategic imbalance with the United States, Soviet Premier Nikita S. Khrushchev began secretly deploying medium- and intermediate-range ballistic missiles to Fidel Castro's Cuba. Once operational, these nuclear-armed weapons could have been used on cities and military targets in most of the continental United States. Before this happened, however, U.S. intelligence discovered Khrushchev's brash maneuver. In what became known as the Cuban Missile Crisis, President John F. Kennedy and an alerted and aroused American government, military, and public compelled the Soviets to remove not only their missiles, but also all of their offensive weapons, from Cuba

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
