Scott and Corey each had a collection of wind-up toys. Corey had 2/9 as many wind-up toys as Scott. When Scott lost 32 wind-up toys, Corey then had twice as many as Scott. How many wind-up toys were in Scott's collection at first?

c = 2/9 s

 

c = 2 ( s-32)         these are given......sub in the first equation to the second

 

2/9 s = 2 (s-32)

2/9 s = 2s - 64

16/9 s = 64

s = 64 * 9 / 16 = 36   originally
