12-16=4y%2B8%2B3y Start with the given equation.


-4=4y%2B8%2B3y Combine like terms on the left side.


-4=7y%2B8 Combine like terms on the right side.


0=7y%2B8%2B4 Add 4 to both sides.


-7y=8%2B4 Subtract 7y from both sides.


-7y=12 Combine like terms on the right side.


y=%2812%29%2F%28-7%29 Divide both sides by -7 to isolate y.


y=-12%2F7 Reduce.

Answer:

So the solution is y=-12%2F7
