A bag of marbles is divided among Alvin and Theodore in the ratio of 2:3. After Alvin gives 2 marbles to Theodore, the ratio becomes 3:5. Find the original number of marbles that was shared among the two friends.

a/t = 2/3        a = 2/3 t

 

(a-2 )/(t+2) = 3/5

a-2 = 3/5 (t+2)        sub in the red equation

2/3t -2  = 3/5 (t+2)    solve for t     then you can solve for   a = 2/3 t     then add them together for the total
