6+2\left(-\frac{y}{5}\right)=y
Use the distributive property to multiply 2 by 3-\frac{y}{5}.
6+\frac{-2y}{5}=y
Express 2\left(-\frac{y}{5}\right) as a single fraction.
6+\frac{-2y}{5}-y=0
Subtract y from both sides.
\frac{-2y}{5}-y=-6
Subtract 6 from both sides. Anything subtracted from zero gives its negation.
-2y-5y=-30
Multiply both sides of the equation by 5.
-7y=-30
Combine -2y and -5y to get -7y.
y=\frac{-30}{-7}
Divide both sides by -7.
y=\frac{30}{7}
Fraction \frac{-30}{-7} can be simplified to \frac{30}{7} by removing the negative sign from both the numerator and the denominator.
