Question 538555
Let's use N as the number requested.


The information provided is:

A number divided by 4, So N/4

Then subtracted by 3. 


So,

N/4 - 3


The result is Zero.


Then we have:

N/4 - 3 = 0  (Equation)


Add 3 to both sides of the Equation.


N/4 - 3 + (3) = 0 + (3)
N/4 + 0 =  3
N/4  =  3


Now, to remove the 4 in the denominator, we multiply by 4 both sides of the previous equation.


N/4 * 4 =  3 * 4
N =  3 * 4
N =  12


The answer is 12.


To prove this answer is correct, we can substitute N by its value 12 in this equation N/4 - 3 = 0  


N/4 - 3 = 0  
12/4 - 3 = 0 
3 - 3 = 0 

0 = 0

The equality is correct, which means the value N = 12 is also correct.
