1%28y-9%29-1%28y%2B4%29=3y Start with the given equation.


y-9-y-4=3y Distribute.


0y-13=3y Combine like terms on the left side.


0y=3y%2B13 Add 13 to both sides.


0y-3y=13 Subtract 3y from both sides.


-3y=13 Combine like terms on the left side.


y=%2813%29%2F%28-3%29 Divide both sides by -3 to isolate y.


y=-13%2F3 Reduce.

Answer:

So the solution is y=-13%2F3
