Answer 2

Answer:

present age of Jacob is 40  years and that of his son his 10 years.

Step-by-step explanation:

Let the present age of Jacob is x years and that of his son his y.

After, 5 years,

Jacob's age = (x+5)

His son's age = (y+5)

Now, from the given direction

x+5 = 3(y+5)

x + 5 = 3y +15

x - 3y = 10 ................(i)

Before, 5 years,

Jacob's age = (x-5)

His son's age = (y-5)

Now, from the given direction

x-5 = 7(y-5)

x - 5 = 7y - 35

x - 7y = -30................(i)

Add equations (i) and (ii)

4y = 40

Divide both sides by 4

y = 10

Substituting the value in (i)

x - 70 = -30

x = -30+ 70

x = 40

Therefore, we have

present age of Jacob is 40  years and that of his son his 10 years.
