Answer:
<em>x=8</em>
Step-by-step explanation:
We have to write and equation for this. We will say that x is the unknown. Let's work backwards: 5 more than half the number. That is 1/2x+5. We will put that on one side. The other side is this: 15 less than 3 times the number. This is 3x-15. Then, we put it together: 3x-15 = 1/2x+5. First, subtract 5 from both sides. Then multiply both sides by two. You will get 6x-40 = x. Then add 40 to get 6x = x+40. Subtract x from the sides: 5x = 40. x=8
