<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the sits in the first aircraft, b represent the second aircraft and c represent the third aircraft.
The first aircraft has 88 more seats than the second aircraft. Hence:
a = b + 88 (1)
Also, The third aircraft has 16 fewer seats than the second aircraft:
c = b - 16 (2)
If their total number of seats is 384:
a + b + c = 384 (3)
From the three equations:
a = 192, b = 104, c = 88
The first aircraft had 192 seats, the second aircraft had 104 seats and the third aircraft had 88 seats
