Answer 2

$x = \frac{15}{4}$

$x = 3.75$

Answer 3

To solve the equation for x, you can start by simplifying both sides of the equation and then isolating x. Here's the step-by-step process:

1. First, combine like terms on both sides of the equation:

   8x + 2x - 5 = 40 + 2x - 15

   This simplifies to:

   10x - 5 = 25 + 2x

2. Next, move all the terms with x to one side of the equation and the constants to the other side. You can do this by subtracting 2x from both sides of the equation:

   10x - 2x - 5 = 25 + 2x - 2x

   This simplifies to:

   8x - 5 = 25

3. Now, isolate the term with x by adding 5 to both sides of the equation:

   8x - 5 + 5 = 25 + 5

   This simplifies to:

   8x = 30

4. Finally, to solve for x, divide both sides by 8:

   (8x) / 8 = 30 / 8

   This simplifies to:

   x = 3.75

So, the solution to the equation is x = 3.75.
