Question

Formulate and write the linear equation in two variables for the following situation:2 years ago, Salim was thrice as old as his daughter and six years later, he will be four years older than twice her age. ​

Answer 1

Answer:

Let the present age of salim be x and age of his daughter be y

2 years ago age of salim=x-2

age of daughter=y-2

(x-2)=3(y-2)

x-3y=-4

after 6 years

x+6=4+2(y+6)

x-2y=10

Upon solving the above two equations we get

y=14

x=38
