Variable $y$ cannot be equal to $\frac{1}{3}$ since division by zero is not defined. Multiply both sides of the equation by $10\left(3y-1\right)$, the least common multiple of $2-6y,5$.
$$-5\left(3y+4\right)=-4\left(3y-1\right)$$
Use the distributive property to multiply $-5$ by $3y+4$.
$$-15y-20=-4\left(3y-1\right)$$
Use the distributive property to multiply $-4$ by $3y-1$.
