Okay, let’s solve this step-by-step:

1. We want to solve the equation 2x + 5 = 15 for x.
2. To isolate x, we need to get the 5 on the other side of the equation.
3. To do that, we subtract 5 from both sides:
   2x + 5 – 5 = 15 – 5
4. Simplifying, we get:
   2x = 10
5. Finally, to solve for x, we divide both sides by 2:
   x = 10/2
6. Therefore, the solution is x = 5.
