Question 1073358
.
 « I'm three times as old as you were when I was as old as you are now. When you will be my age, together we will be 13370 years old. »
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let M = my age now
Let Y = your age now,

so my variables are consistent with those of Edwin McCravy.


When it was happened when "I was as old as you are now" ? 
Obviously, it was (M-Y) years ago.

So, your first equation is

M = 3*(Y-(M-Y)).                     (1)


Now, when "you will be my age" ? - Obviously, in (M-Y) years.
Therefore, your second equation is 

(M + (M-Y)) + (Y + (M-Y)) = 13370.   (2)


The rest is just a technique.


<U>Answer</U>. M = 5730, Y = 3820.
