Question

09. Two years later, a father will be 8 years more than three times the age of his son. Taking the present ages of father
and son as x and y respectively, write a linear equation for the above condition and draw its graph,
From the graph, find the age of the father, when the son's age is 10 years.​

Answer 1

Answer:

Suppose, present age of father = x years and present age of son = y years

Two years later,

Age of father = (x + 2) years

Age of son = (y + 2) years

Two years later, age of father = 3 × Age of son + 8 years  [Given]

When age of son, y = 10 years, age of father, x = 3 × 10 + 12 = 30 + 12 = 42 years.
