Question

What number gives a result of -2 when 9 is subtracted from the quotient of the number and 5?

Answer 1

let the number be n
the quotient is the result of the division.
so dividing n by 5 and then subtracting 9 gives us -2. This can be written in the form of an equation as follows:
n/5 - 9 = -2 (multiply all terms by 5)
n - 45 = -10
n = -10+45 = 35
