Solve the equation. Don't forget to first simplify each side of the equation, if possible.
-$\frac { 5 } { 6 } y + \frac { 5 } { 9 } = - \frac { 1 } { 6 } y - \frac { 5 } { 6 }$
A) $\frac { 25 } { 18 }$
B) $- \frac { 25 } { 18 }$
C) $- \frac { 5 } { 18 }$
D) $- \frac { 2 } { 3 }$

To solve the equation, first combine like terms. Adding $\frac{1}{6}y$ to both sides gives $\frac{5}{6}y + \frac{1}{6}y = -\frac{5}{6} - \frac{5}{9}$. Simplifying the left side yields $\frac{6}{6}y = \frac{10}{6}y$, which simplifies to $y$. Adding the fractions on the right side, we get $-\frac{30}{18} - \frac{10}{18} = -\frac{40}{18}$, which simplifies to $-\frac{20}{9}$. Multiplying both sides by the reciprocal of the coefficient of $y$ (which is 1 in this case, so it doesn't change the equation), we find $y = -\frac{20}{9}$. However, there seems to have been a miscalculation in the simplification process. Correctly combining and simplifying the terms should lead to $y = -\frac{25}{18}$, which matches option B.
