Answer 2

To solve the equation -x = 15 and 4/7, we need to isolate the variable x. Let's go through the steps:

1. Start with the equation -x = 15 and 4/7.
2. To get rid of the negative sign, multiply both sides of the equation by -1: x = -(15 and 4/7).
3. To convert the mixed number 15 and 4/7 to an improper fraction, we multiply the whole number (15) by the denominator (7) and add the numerator (4) to get the new numerator. The denominator remains the same. So, 15 and 4/7 becomes (15 * 7 + 4)/7 = (105 + 4)/7 = 109/7.
4. Therefore, the solution to the equation -x = 15 and 4/7 is x = -109/7.

So, x is equal to -109/7.
