Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Two classmates, Brittany and Quinn, plan to meet in the computer lab to type up their research papers. Brittany can type at a speed of 3 pages per hour, whereas Quinn can type 1 page per hour. So far, Brittany already has 4 pages typed up, compared to Quinn's 14 pages. Once they sit down and start typing together, the two students will reach the same page count before too long. How long will that take? What will the page count be?
