56 less than the quotient of a number and 4 is - 52. What is the value of the unknown number?

16

Step-by-step explanation:

The quotient of a number (x) and 4 is written x/4. 56 less than that is ...

(x/4) - 56

The problem statement tells us the value of this is - 52, so we have ...

(x/4) - 56 = - 52

Add 56 to both sides of this equation, and you get ...

x/4 = 4

Multiply both sides of this equation by 4 and you get ...

x = 16

The value of the unknown number is 16.
