Need help with a question guys, any help will be most appreciated.

The age of a machine, x, in years, is related to the probability of breakdown, y, by the formula:

x = 3 + ln(y/1-y)

Determine the probability of breakdown for 1, 3 and 10 years.

Where do I start with this one?

It has got me a bit stumped guys so any help would be most appreciated.

Thanks
