Question 1085564
.
<pre>
xy = yx   is ALWAYS TRUE for real numbers due to commutativity property of multiplication.

          Therefore, this identity does not bring any restrictive information to you.


The only restriction/equation is y = 3x, and it implies x =  {{{y/3}}}.
</pre>

<U>Answer</U>. From the given condition, x = {{{y/3}}}.
