Four years ago, Katie was twice as old as Anne was then. In 6 years , Anne will be the same age that Katie is now. How old is each now?

A = anne now      4 years ago Anne was A-4

K = Katie now        four years ago Katie was    K-4  and this = 2(A-4)

 

In SIX years   A+6 = K

 

Two equations, two unknowns....solve for A  and K

 

K-4 = 2(A-4)

(A+6)-4 = 2A-8

10 = A                         K = A+6 = 16 y/o
