Does anyone get

15 less than 3 times a number is the same as 5 more than half of the number. what is the number?

Hello from MrBillDoesMath!

8

Discussion:

Let the number be "n". Then the question states that

3n - 15 = (n/2) + 5             => multiply both sides by 2

6n - 30 = n + 10                => subtract n from both sides

5n - 30 = 10                      => add 30 to both sides

5n = 30 + 10 = 40            => divide both sides by 5

n = 40/5 = 8
