Jacob and Austin each had a collection of baseball cards. The ratio of Jacob's baseball cards to Austin's baseball cards was 4:1. When Austin found 35 more baseball cards, the ratio became 1:2. How many baseball cards did Jacob have?

j = 4 a

 

then

2j = (a+35)      sub in the first equation

2 ( 4a) = a + 35

7a = 35

a=5        j = 4 a = 20 cards originally
