10+250p+150p=50
Add 150p to both sides.
10+400p=50
Combine 250p and 150p to get 400p.
400p=50-10
Subtract 10 from both sides.
400p=40
Subtract 10 from 50 to get 40.
p=\frac{40}{400}
Divide both sides by 400.
p=\frac{1}{10}
Reduce the fraction \frac{40}{400} to lowest terms by extracting and canceling out 40.
