In 1492, Christopher Columbus journeyed to the New World, where he explored portions of the coast of two large Caribbean islands, Cuba and Hispaniola. Cuba is the larger of the two islands. Cuba is 10,000 square miles larger than Hispaniola. Hispaniola is only as large as Cuba. The equation below, where x is the area of Cuba in square miles, expresses this relationship.

x − 10,000 = x

What is the area of Cuba, in square miles?
