Answer:

2

Explanation:

Let's say the number is "n".

"n" stands for the unknown number in this instance.

When n is 3 times itself (written as 3n), it is equal to half of itself added to five. That would make the equation 3n=1/2n+5. Then, subtract like terms. 3n-1/2n=1/2n-1/2n+5 ----> 2 1/2n (aka 5/2n) = 5, then, multiply both sides by 2/5 (the inverse of 5/2) to get n=2.
