four times a number decreased by four is 8

Answer 1

Let's call the number x.

According to the problem, we have the equation:

4x - 4 = 8

To solve for x, we can start by isolating the variable on one side of the equation. We can do this by adding 4 to both sides:

4x - 4 + 4 = 8 + 4

Simplifying, we get:

4x = 12

Now, we'll divide both sides by 4 to solve for x:

(4x)/4 = 12/4

Simplifying further, we have:

x = 3

Therefore, the number is 3.
