There's several ways to solve any equation. Because the denominators in the fractions are different, let's find the LCD (in this case, it's 15), and multiply both sides of the equation by it. Doing so yields 15-10y=27-3y+9}}}, which reduces to 15-10y=36-3y. Adding 10y to both sides gives 15=36+7y and subtracting 36 from both sides gives -21=7y. Finally dividing by 7 on both sides gives us -3=y.
