What is an equation?
An equation is an expression that shows the relationship between two or more number and variables.
Let x represent the speed of the airplane, in miles per hour, when there is no wind, b represent the time spent going and c represent the time spent travelling back. Hence:
(x + 20)b = 350 (1)
Also:
(x - 20)c = 350 (2)
b + c = 6 (3)
The equation that represents this situation (x + 20)b = 350, (x - 20)c = 350 and b + c = 6
