Tom had \( {2 \over 3}{}{} \)as many stickers as Edward at first. After Tom bought another 8 stickers and Edward lost 5 stickers, Tom had \( {4 \over 5}\)as many stickers as Edward. Find the number of stickers Tom had at first.

t = 2/3 e      or    e = 3/2 t

 

t+8 = 4/5 (e-5 )        sub in the red equation

 

t + 8 = 4/5 (3/2 t-5)     solve for t
