Andy = a
Kate = k
a = 2k
2k + k = 60
3k = 60
k = 20
Kate will be 20 and Andy will be 40 in 6 years. Minus 6 years:
k = 20 - 6 = 14
a = 40 - 6 = 34
Currently, Kate is 14 and Andy is 34.
Hope this helps!

Andy = A
Kate = K
A = 2K
2K + K = 60 (in 6 years)
A+6 + (K+6) = 60
2K + 6 + K + 6 = 60
3K = 48
Kate = 16 yrs old
Andy = 32 yrs old
