12%28y-1%29-4y=3%282y-2%29%2B9y Start with the given equation.


12y-12-4y=6y-6%2B9y Distribute.


8y-12=6y-6%2B9y Combine like terms on the left side.


8y-12=15y-6 Combine like terms on the right side.


8y=15y-6%2B12 Add 12 to both sides.


8y-15y=-6%2B12 Subtract 15y from both sides.


-7y=-6%2B12 Combine like terms on the left side.


-7y=6 Combine like terms on the right side.


y=%286%29%2F%28-7%29 Divide both sides by -7 to isolate y.


y=-6%2F7 Reduce.


----------------------------------------------------------------------

Answer:

So the solution is y=-6%2F7 which approximates to y=-0.857.
