You can
put this solution on YOUR website!A is eleven times as old as B.
A = 11B
-------------
in a certain number of years, A will be five times as old as B
A+x = 5(B+x)
-------------
and in five years after that she will be three times as old as B.
A+x+5 = 3(B+x+5)
-----------------
how old are they now?
-------
Rearrange the three equations with variables A, B, and x
A - 11B + 0x = 0
A - 5B -4x = 0
A -3B - 2x = 10
---------------
Solve the systems of three equations by any method to get:
A = 22
B = 2
x = 3
-----------
A is 22 yrs. old
B is 2 yrs. old
