First aircraft seats : x
second aircraft seats : y
third aircraft seats : z
<span>The first aircraft has 73 more seats than the second aircraft: x = y + 73
</span>
<span>The third aircraft has 57 fewer seats than the second aircraft: z = y - 57
</span>
<span>Their total number of seats is 427: x + y + z = 427
solve these three equations, you will get:
x = 210 seats
y = 137 seats
z = 80 seats
-------------------------
you can check your answer by:
x - y = 210 - 137 = 73 correct
and
z + 57 = 80 + 57 = 137 = y correct

Answer:
just take the 96 and 66 and middle it then take y multiply that=answer
Step-by-step explanation:
5.75a + 6.5c = 53.25
a + c = 9
c = 9 - a
5.75a + 58.5 - 6.5a = 53.25
5.25 = 0.75a
a = 7
7 + c = 9
c = 2
