15x−6y=54

To solve for y, we need to isolate y on one side of the equation.

15x - 6y = 54

First, subtract 15x from both sides of the equation to move the term containing x to the other side:

-6y = -15x + 54

Then, divide both sides of the equation by -6 to solve for y:

y = (-15x + 54) / -6

Simplifying the right side of the equation further:

y = (-15x)/-6 + 54/-6

y = (5/2)x - 9
