Joyce and Kaylene had some stickers. The number of stickers Joyce had was 4/5 of what Kaylene had. Joyce then gave 5/8 of her stickers to Kaylene. As a result, Kaylene had 108 more stickers than Joyce. How many stickers did Joyce have at first?
Initially j = 4/5 k or k = 5/4 j
j - 5/8j + 108 = k + 5/8 j sub in red equation
3/8 j + 108 = 5/4j + 5/8 j
108 = 12/8 j
j = 72
