Question

Kevin is 6 years older than Timothy. 4 years ago, Kevin was twice as old as Timothy. Find their present ages.

Answer 1

k=12

t=8

Explanation:

two equations from the question

1 k=t+6

2 (k-4)=(t-4)×2

develop these

3. k-4=2t-8

4. 2 times first equation

2k=2t+12

subtract 4 from 3

-k-4=-20

k=16

sub back in

t=10
