let mother be x years and son be y years now
After 14 years
(x+14)=2(y+14)
x+14=2y+28
x-2y=14.......................(1)
4 years ago
(x-4) +(y-4) =30
x+Y-8=30
x+y = 38.......................(2)
subtract (2) from (1)
-3y=-24
y=8
Therefore x=30 because x+y=38
Son was born 8 years ago
so mother was 30-8 = 22 years then
