87 less than the quotient of an unknown number and 43 is -75.

What is the value of the unknown number?

Help + explanation? I don't understand whether the 43 is the numerator or "the unknown number" (x) is. How do you know which is the numerator and which is the denominator

Let N be the unknown number..."quotient"  means "divided by"...so we have......

 

N /  43 - 87  = -75      add 87 to both sides

 

N / 43   =  12        multiply both sides by 43

 

N = 516
