Kate in two years will be 8 because M is 4 now. So two years from now Kate will be twice as old. Not real timeframe or else M would age just as much as Kate so Kate can never be twice as old. So Kate is 6 now plus 4 equaling 10.

T= k+4
but
k= (m2) +2
if m is 4
k= (42)+2
k=10
but T=K+4
T=10+4
=14

Set up a simple equation: T = K + 4 K + 2 = 2 (M + 2) M = 4 Substitute 4 for M. K + 2 = 2 (4 + 2) K + 2 = 2 6 K + 2 = 12 K = 10 Then substitute 10 for K. T = K + 4 T = 10 + 4 T = 14
