Решение:

$\frac{5(x-y)}{15(y-x)}=\frac{5x-5y}{15y-15x}$

Answer 2

To solve the equation, let's simplify it step by step:

1. Distribute the 5 on the left side and the 15 on the right side: 5x - 5y = 15y - 15x

2. Add 15x to both sides of the equation: 5x + 15x - 5y = 15y - 15x + 15x

Simplifying further, we get: 20x - 5y = 15y

3. Add 5y to both sides of the equation: 20x - 5y + 5y = 15y + 5y

Simplifying further, we get: 20x = 20y

4. Divide both sides of the equation by 20 to isolate x: (20x)/20 = (20y)/20

Simplifying further, we get: x = y

Therefore, the solution to the equation 5(x - y) = 15(y - x) is x = y.
