Question

What number gives a result of −1 when 9 is subtracted from the quotient of the number and 4?

Answer 1

32

Explanation:

(Quotient of a and b = a/b)

Let the number = x

Quotient of the number and four: x/4

9 subtracted from the quotient of the number and four: x/4 - 9

-1 is the result of 9 subtracted from the quotient of the number and four: x/4 - 9 = -1

x/4 -9 = -1

x/4 = 8

x = 32

Answer 2

Explanation:

x/4 - 9 = -1

×/4 = -1 + 9

x/4 = 8

4 (x/4) = 4 (8)

x = 32
