Question 135071: Systems of Linear Equations
The probability that San Francisco plays in the next Superbowl is nine times the probability that they do not play in the next superbowl. The probability that San Francisco plays in the next Super Bowl plus the probability that they do not play is 1. What is the probability that San Francisco plays in the next Super Bowl?

You can put this solution on YOUR website!
Probability that they play: P%5Bp%5D
Probability that they do not play: P%5Bn%5D

P%5Bp%5D=9P%5Bn%5D and P%5Bp%5D%2BP%5Bn%5D=1, so by substitution:

9P%5Bn%5D%2BP%5Bn%5D=1

Can you take it from here or do you need more help?
