Answer 2

To solve the equation (x + 5) · D = 3x + 15, you can follow these steps:

1. Distribute D to both terms inside the parentheses on the left side of the equation:

   D(x) + 5D = 3x + 15

2. Move all the terms containing x to one side of the equation and the constant terms to the other side. You can do this by subtracting 3x from both sides and subtracting 15 from both sides:

   D(x) - 3x + 5D - 15 = 0

3. Now, the equation should look like this:

   D(x) - 3x + 5D - 15 = 0

4. At this point, you may not be able to solve for x because you have both D (which seems to be a constant) and x (which is the variable) in the equation. If you have a specific value for D, you can solve for x. Otherwise, you'll need more information about D to find a specific solution for x.

If you have a specific value for D, please provide it, and I can help you find the solution for x.
