Question

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Daniel now?

Answer 1

K=3+D

K-2 = 4(D-2) = 4D -8

K = 4D -6

3+D = 4D -6

3D = 9

D = 9/3 = 3 years old for Daniel

K = 3+3 = 6 years old for Kevin

2 years ago they were 1 and 4 years old

4 = 4(1)
