3x+6y-\left(3x-2\right)=-4
Multiply both sides of the equation by 3.
3x+6y-3x+2=-4
To find the opposite of 3x-2, find the opposite of each term.
6y+2=-4
Combine 3x and -3x to get 0.
6y=-4-2
Subtract 2 from both sides.
6y=-6
Subtract 2 from -4 to get -6.
y=\frac{-6}{6}
Divide both sides by 6.
y=-1
Divide -6 by 6 to get -1.
