Question

the age of father is 3 yrs more than three times the age of his son . three yrs hence .father's age will be ten yrs more than twice the age of his son...assuming father's age as x and son's age as y form two linear equations...

Answer 1

Given Father's age is x
and son's age is y

• age of father is 3 years more than three times the age of his son

x = 3 + 3y

x - 3y = 3 ... ( i )


• After three years

father's age :- x + 3
Son's age :- y + 3

• Father age is now 10 years more than twice the age of his son

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

x + 3 = 10 + 2y + 6

x - 2y = 16 - 3

x - 2y = 13 ..... ( ii )


So, ( i ) & ( ii ) are required linear equation.

Answer 2

solve this equations
