Final answer:
To add 15 and (1/x), rewrite 15 as 15x/x and add the fractions to get (15x + 1)/x. The result is already simplified.
Step-by-step explanation:
To add 15 and (1/x), we need a common denominator. The denominator of 15 is x, so we can rewrite 15 as 15x/x. Now we can add the fractions: (15x + 1)/x. If possible, simplify the result further by factoring out the common factor. In this case, the result is already simplified.
