You can put this solution on YOUR website! Hi there,
Andy is twice as old as Kate
A = 2K
in 6 years, their ages will total 60
(A + 6) + (K + 6) = 60
Replace A with 2K
(2K + 6) + (K + 6) = 60
Remove brackets
2K + 6 + K + 6 = 60
Collect like terms
2K + K = 60 - 6 - 6
3K = 48
K = 16
Kate is 16 yrs old
Andy is 32 yrs old
Hope this helps :-)
