Answer 3

To solve the equation (2.5 - 3.5x) = 19.5 - 2.5(5 + 2x), follow these steps:

1. Distribute the -2.5 on the right side of the equation:

   2.5 - 3.5x = 19.5 - 12.5 - 5x

2. Combine like terms on both sides of the equation:

   2.5 - 3.5x = 7 - 5x

3. Add 5x to both sides to isolate the x terms on one side:

   2.5 - 3.5x + 5x = 7 - 5x + 5x

   2.5 + 1.5x = 7

4. Now, subtract 2.5 from both sides to isolate the term with x:

   2.5 + 1.5x - 2.5 = 7 - 2.5

   1.5x = 4.5

5. Finally, divide both sides by 1.5 to solve for x:

   (1.5x) / 1.5 = 4.5 / 1.5

   x = 3

So, the solution to the equation is x = 3.
