You can put this solution on YOUR website!
x%2F%2812-x%29=5%2F15 Start with the given equation.


15x=5%2812-x%29 Cross multiply.


15x=60-5x Distribute.


15x%2B5x=60 Add 5x to both sides.


20x=60 Combine like terms on the left side.


x=%2860%29%2F%2820%29 Divide both sides by 20 to isolate x.


x=3 Reduce.

Answer:

So the solution is x=3


I leave the check for you.
