To solve this problem, let's set up an equation, letting n represent the number that you are trying to find.
n/2 - 4 = 2
To begin simplifying this equation, you must add four to both sides.
n/2 = 6
Finally, we must multiply both sides by two, in order to get rid of the denominator of the variable n.
n = 12
We know that this answer is correct because if we plug the value 12 back into the beginning equation for the variable n, it results in a true statement.
Thus, the number is 12.
Hope this helps! :)
