For a certain bottle and cork, what is the price of the cork?
Let x and y be the price of bottle and cork respectively
(1) The combined price of the bottle and the cork is 95 cents -->x+y=95....insufficient
(2) The price of the bottle is 75 cents more than the price of the cork -->x-y=75.....insufficient
1+2 -->x=85 and y=10.....sufficient
Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time. - Thomas A. Edison
