Let's call the number "x".
The equation for "four times a number, decreased by 4" is:
4x - 4 = 8
Now let's solve for x:
Add 4 to both sides of the equation:
4x - 4 + 4 = 8 + 4
This simplifies to:
4x = 12
Divide both sides of the equation by 4:
4x/4 = 12/4
This simplifies to:
x = 3
Therefore, the number is 3.
