Question 4868
In this question we have to make equation and solve the equation.

SO how to make the equation in the first step.

We have to find ages of two persons   Tyrone and his daughter.

LET us suppose that there present ages are   

Tyrone --  x years   and Daughter  y years

we get the first equations as

        x = 2y   ------  (1)

Now what will be Tyrone's age after 6 years ?   YES  (x + 6)
       and his daughter's age 6 years ago   ?   YES  (y - 6)

So we get the second equation as 

       (x + 6)  = 3(y - 6)  ---  (2)
       
Now putting the value of x from (1) in (2) we get

       (2y + 6) = 3(y - 6)
        2y + 6  = 3y - 18
Bringing the terms with y on one side and the remaining terms on other side we get
        2y - 3y = -18 -6
          -y = -24
  Cancelling - from both sides we get 

     y = 24

Putting value of y= 24 in (1)  we get

         x = 2(24) = 48

So age of Tyrone is 48 years  and his daughter's age is 24
