p-3p/8=9

p-3p=72

-316

I am not sure if I did this right. Just guessing.

You should have made the denominators alike so that you could subtract the fractions easier.

p/3-3p/8=3

8p/24 - 9p/24 = 3

-p/24 = 3

-p= 3(24)

-p= 72

-p/-1 = 72/-1

p=-72

multiply each term by the LCD, which is 24, so

8p - 9p = 72

-p = 72

p = -72
