Even if you extend the domain to complex numbers, there are no solutions. The f(x) = |x| function always returns a positive real value, even for complex numbers.
The Brady family received 1 letter on July 28.
Step-by-step explanation:
Step 1:
Assume a = the number of letters, b = the number of bills, c = the number of ads, and d = the number of magazines.
From the question, they got 15 pieces of mail that day so 
They got 5 more magazines than bills so 
The got the same number of letters as ads so 
They got 3 more bills than ads so 
Step 2:
As we have only one equation to solve the values, we need to make every term in terms of a single term.
We make everything in terms of c.
So 
Substituting all this in the equation, we get


Step 3:
Substituting c = 1 in other terms, we get


and

As a = 1, they received 1 letter that day.
