⟹y=4x...........eq(1)

According to 2nd condition :-

After 8 years, George will be twice as old as John.

After 8 years,

Age of George = (y+8) years

Age of John = (x+8) years

⟹

⟹y+8=2(x+8)

Put y = 4x from eq(1).

⟹y=16

Therefore, the present age of George is 16 years.

Answer:

16

Step-by-step explanation:

y+8=2

if you do it easily then

y is equal to 8 multiply by 2

then the answer is 16
