hey

Let the age of sons be x&that of fathers be y.
2x+y=70.................(1)
x+2y=95......................(2)
by adding equation no. (1)&(2)
3x+3y=165
x+y=55...................(3)
subtracting eq no.(2) from (1)
x-y=-25.................(4)
adding eqno. (3)&(4)
2x=30
x=15
substituting x=15 in eqno.(3)
y=40
son's age is 15&father's age is 40
