Answer 1

Answer:

2x equal to y

Step-by-step explanation:

Because after 2 years father is be twice as old as his son.

Answer 2

Answer:

after ten years

age of son = (X+10)

age of father = (Y+10)

if father is twice as old as his son

so,

2(X+10) = (Y+10)

2X+20 = (Y+10)

2X+20-(Y+10) =0

2X+20-Y-10 = 0

2X-Y+10 = 0

hence relation between X and Y is

2X-Y+10 = 0
