6\left(-2y-1\right)-3y=-5
Multiply both sides of the equation by 6, the least common multiple of 2,6.
-12y-6-3y=-5
Use the distributive property to multiply 6 by -2y-1.
-15y-6=-5
Combine -12y and -3y to get -15y.
-15y=-5+6
Add 6 to both sides.
-15y=1
Add -5 and 6 to get 1.
y=\frac{1}{-15}
Divide both sides by -15.
y=-\frac{1}{15}
Fraction \frac{1}{-15} can be rewritten as -\frac{1}{15} by extracting the negative sign.
