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
