Write a system of equations that can be used to solve the following problem. Then solve the system and determine the answer. Jaafar owns a total of shares of stock, some in stock A and some in stock B. On a particular day, stock A closed at $ per share and stock B closed at $ per share. If Jaafar's stock for these companies was worth $, how many shares of each type of stock does he own? Let x denote the number of shares of stock A that Jaafar owns. Let y denote the number of shares of stock B that Jaafar owns. Write the equation corresponding to the first sentence of the problem statement ("Jaafar owns a total of shares of stock"). The first equation is nothing. Write an equation relating x and y that corresponds to the second and third sentences of the problem statement. The second equation is nothing. Jaafar owns nothing shares of stock A and nothing shares of stock B. g
