Answer 3

To solve the equation 8 * 0.5²x + 31 * 0.5x - 4 = 0, you can follow these steps:

1. First, simplify the terms with common factors:

   4x + 15.5x - 4 = 0

2. Combine like terms:

   19.5x - 4 = 0

3. Add 4 to both sides of the equation to isolate the term with x:

   19.5x = 4

4. Finally, divide both sides by 19.5 to solve for x:

   x = 4 / 19.5

You can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 0.5:

x = (4 / 0.5) / (19.5 / 0.5) x = 8 / 39

So, the solution to the equation is x = 8/39.
