Answer 1

hey!

here is. answer

let the age of. father be y

and age of son be x


case 1

a/q

x-2=y-2

3(x-2)=y-2

3x-6=y-2

3x-y=-2+6

3x-y=4...............(1)


case 2

a/q

2+x=2+y

5(2+x)=2+y

10+5x=2+y

5x-y=2-10

5x-y=-8..........(2)


from equation (1) and (2)

3x-y=4
5x-y=-8
_______

2x=12

x=12/2

x=6


put the value of x in equation 2

5(6)-y=-8

30-y=-8

-y=-8-30

-y=-38

y=38




hope it helps.
