Given that x represents the input and y represents the output
Translate the statement from math to English.
Therefore “output” means y and “input” means x, so the only other thing you need to know is “is” means = (equals):
a) When the output is five more than the input therefore (Output)x= (Input)5y
x = 5y
b)When the output is four more than twice the input.
x = 4y + 2
