Answer:
n/5 - 11 = -13
Step-by-step explanation:
We must do the division first, before the subtraction:
"the quotient of a number and 5" is n/5."
"11 subtracted from this result" comes out to n/5 - 11 = -13.
This is the answer. We were not asked to simplify it. But if we want to simplify it, we add 11 to both sides, obtaining n/5 - 2.
