Answer 1

Answer:

Solution 2

Let the present age of Aftab and his daughter be x and y respectively.

Seven years ago,

Age of Aftab = x - 7

Age of his daughter = y - 7

According to the given condition,

Three years hence,

Age of Aftab = x + 3

Age of his daughter = y + 3

According to the given condition,

Thus, the given conditions can be algebraically represented as:

x - 7y = -42

x - 3y = 6

Three solutions of this equation can be written in a table as follows:

x -7 0 7

y 5 6 7

Three solutions of this equation can be written in a table as follows:

x 6 3 0

y 0 -1 -2
