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.
