Let's let the number be x. The equation would be:
4x - 4 = 8
To solve for x, we need to isolate it on one side of the equation. We can do this by adding 4 to both sides.
4x - 4 + 4 = 8 + 4
This simplifies to:
4x = 12
Now we can solve for x by dividing both sides by 4.
4x/4 = 12/4
x = 3
Therefore, the answer is A. 3.
