ble age of his son. Find their present age.​

Answer 1

Answer:

Present age of son is 10

Present age of father is 33

Step-by-step explanation:

Let the present age of son be X

And the present age of the father be Y

According to the question

Y=3x+3

Also according to the question

Y+3=(x+3)2 +10

=} Y= 2x+6+10-3

=} Y=2x+13

Substituting the first equation into the second we get

3x+3=2x+13

=}3x-2x=13-3

=} X=10

=} Y= 3×10+3

= 33

Therefore

Present age of son=10

Present age of father=33
