Eight less than the product of a number n and
is no more than 94.

First, let's call "a number": n

Then. "eight less than a number" can be written as: n-8  

This expression "is no more than 14" can be written as: n−8≤14

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

y = -1

x = 8

hope this !
