3\left(1-3y\right)-4y=16
Multiply both sides of the equation by 2.
3-9y-4y=16
Use the distributive property to multiply 3 by 1-3y.
3-13y=16
Combine -9y and -4y to get -13y.
-13y=16-3
Subtract 3 from both sides.
-13y=13
Subtract 3 from 16 to get 13.
y=\frac{13}{-13}
Divide both sides by -13.
y=-1
Divide 13 by -13 to get -1.
