together, a Delta B747 and a Delta B777 seat 681 passengers. if the B777 seats 125 less people than the B747, how many passengers does it seat?

Answer provided by our tutors

let


x = the number of passengers Delta B747 seats


y = the number of passengers Delta B777 seats


together, a Delta B747 and a Delta B777 seat 681 passengers:


x + y = 681


the B777 seats 125 less people than the B747:


y = x - 125


by solving the system of equations:


x + y = 681


y = x - 125


we find:


x = 403 passengers


y = 278 passengers
