Answer:

That number would be -4.

Explanation:

In order to find this, we need to make it into a numerical statement.

nine fewer than half a number is 1/2n - 9

five more than four times the number is 4n + 5

Now we set them equal to each other.

1/2n - 9 = 4n + 5 ----> Subtract 1/2n from both sides

-9 = 3.5n + 5 -----> Subtract 5 from both sides

-14 = 3.5n ------> Divide by 3.5

-4 = n
