10 years hence, A will be twice as old as B was 10 years ago. If A is now 10 years older than B, find the present age of B.
I formed this equation for solving this sum:
x + 9 + 10 = 2(x  10)
Where x + 9 is A's age and x is B's age.
Just wanted to know if I am right.

Best ResponseYou've already chosen the best response.0x + 9 + 10 denotes A's age 10 years hence. It is equal to 2(x  10) which is twice of B's age 10 years ago.

Best ResponseYou've already chosen the best response.0i guess ten years ago from 10 years in the future is the present, lol

Best ResponseYou've already chosen the best response.0But then, they've given 10 years hence for A and 10 years ago for B.

Best ResponseYou've already chosen the best response.0Which is same as mine right? Only thing I've replaced A with x + 9.

Best ResponseYou've already chosen the best response.0x + 9 is A's present age(B's present age is x and A is 9 years older than B) .

Best ResponseYou've already chosen the best response.0Oh, I made a typing mistake its actually if A is 9 years older than B, find B's present age.....
