A electronics company kept comparative statistics on two products, A and B. For the years 1980 to 1988, the total number of Product A ever sold (in thousands) is given by the equation y=72x+270 where x is the number of years since 1980. For that same period, the total number of Product B ever sold (in thousands) is given by the equation y= - 30x + 434, where x is the number of years since 1980. Use the substituion method to solve the system and describe the solution in your own words.
