1.	. Ten years ago, a father was 10 times as old as his son. Form alinear equation expressing their present age.
Answer» Let us consider that the present age of the father and the son are x and y years. So, 10 years ago, the father was (x - 10) years old. Given that : x - 10 = 10y => x - 10y = 10, which is the required linear equation.

. Ten years ago, a father was 10 times as old as his son. Form alinear equation expressing their present age.

Answer»

Let us consider that the present age of the father and the son are x and y years.

So, 10 years ago, the father was (x - 10) years old.

Given that :

x - 10 = 10y

=> x - 10y = 10,

which is the required linear equation.
