Judy is now twice as old as adam, but 6 years ago, she was 5 times as old as he was . How old is Judy now?

Answer 1

J=2A

5(A-6) = J-6

5A-30 = J-6

5A-J = -6+30 = 24

5A -2A = 24

3A = 24/3 = 8 years old for Adam now

J=2(8) = 16 years old for Judy now

6 years ago they were 2 and 10

10 = 5 x 2

16 = 8 x 2
