To solve the equation $4x - 3y = 15$ for $y$, follow these steps:

1. Start with the given equation: $4x - 3y = 15$

2. Subtract $4x$ from both sides: $-3y = 15 - 4x$

3. Divide both sides by $-3$ to isolate $y$: $y = \frac{15 - 4x}{-3}$

4. Simplify the right-hand side: $y = -5 + \frac{4}{3}x$

Thus, the equivalent equation when solved for $y$ is: $y = \frac{4}{3}x - 5$
