In five years, Ana’s age will be twice the age of her friend Jun. Five years ago, she was three times as old as her friend. Find their present ages.

Answer 1

A+5 = 2(J+5) = 2J + 10

A -2J = 5

A-5 = 3(J-5) = 3J-15

A-3J =-10

A-2J = 5

-J =-15

J =15 years old for Jun today

A = 2J+5 = 35 years old for Ana today

in 5 years Anna will be 40 and Jun 20, 40 is twice 20

5 years ago Ann was 30 and Jun 10, 30 is 3 times 10
