Answer 2

To solve the equation (-1/3)X + (-1/4)X + (1/5)X = 1 + (8/15), follow these steps:

1. First, find a common denominator for the fractions on the left-hand side. The common denominator for 3, 4, and 5 is 60.

2. Rewrite the fractions with the common denominator: (-20/60)X + (-15/60)X + (12/60)X = (60/60) + (8/15)

3. Simplify the fractions: (-20/60)X - (15/60)X + (12/60)X = (73/60)

4. Combine the X terms on the left-hand side: (-23/60)X = (73/60)

5. To solve for X, multiply both sides of the equation by the reciprocal of the coefficient of X: X = (73/60) / (-23/60) X = -73/23

So, the solution to the equation is: X = -73/23
