50000+150p-250p=10000
Subtract 250p from both sides.
50000-100p=10000
Combine 150p and -250p to get -100p.
-100p=10000-50000
Subtract 50000 from both sides.
-100p=-40000
Subtract 50000 from 10000 to get -40000.
p=\frac{-40000}{-100}
Divide both sides by -100.
p=400
Divide -40000 by -100 to get 400.
