mrs.montez is 20 years older than Mrs. cooke. sixteen years ago mrs.montez was 3 times as old as mrs. cooke was then. how old are mrs.montez and mrs. cooke now?
let Mrs. cooke's age be x now
mrs. montez's age will be x+20
16 years ago their ages were x-16 and (x+20)-16
Mrs. montez was 3 times mrs. cooke's age then
3(x-16) = (x+20)-16
3x-x = 48+20-16
x=26 that is cooke's age now
Mrs montez's age will be x+20 = 26+20 = 46 years
