In 2009 research showed that the United States and Japan topped the charts in a number of social media and blog users, with a combined number of 188,610 users. The number of social media and blog users in the U. S. was 2,378 more than three times the number of social media and blog users in Japan. Write a system of equations that models the number of social media and blog users for the U. S. and Japan. Let x represent the number of users in the U. S., and let y represent the number of users in Japan. Write the equations and solve them. How many users are there in each country?
