The sum of half a number, n, and 15 is 24. What is the value of the number n? Type your answer in the blank below.

1/2 n + 15 = 24


Answer :

An easy way to do this is subtract 15 form 24 which will look like this 1/2n=24-15
Which gets you 1/2n=9
Then you multiply the equation by 2 to get rid of the 1/2 which gets you just N=18
