You have a bag which contains only red and green marbles. In this bag with x^2+5 marbles total, x+1 are red. Also, x3 marbles have a scratch on them. The probability of drawing a red marble from the original bag is equal to that of drawing a marble with a scratch from the marbles left in the bag after twenty scratchfree marbles are taken out of the full bag. How many marbles were originally in the bag?
