Internet Audience At the end of a certain year, the four companies with the largest number of home Internet users in the United States were Microsoft, Time Warner, Yahoo, and Google, with a combined audience of 284 million users. Taking x to be the Microsoft audience in millions, y the Time Warner audience in millions, z the Yahoo audience in millions, and the Google audience in millions, it was observed that z - u = 3(x - y) + 28 x + y = 46 + z + u and x - y + z - u = 56. How large was the audience of each of the four companies at the end of that year? Microsoft Time Warner Yahoo Google
