Answer 1

Answer:

Step-by-step explanation:Let, the present age of father be x years and that of his son be y years.

As per condition 1 ie., Father is four times as old as his son.

The equation becomes,

x=4y

or

x−4y=0

As per condition 2 i.e., The age of the father at the time of the birth of his son was 30.

The equation becomes,

x−y=30
