.
What if I want to solve the problem using only ONE equation, and not the system ?



----------
&lt;U&gt;N o t i c e&lt;/U&gt;:  &amp;nbsp;&amp;nbsp;The correct way to solve it is not using a system.


It is using a &amp;nbsp;&lt;U&gt;SINGLE&lt;/U&gt;&amp;nbsp; equation.


But you can make your life &amp;nbsp;&lt;U&gt;as complicated as you want&lt;/U&gt;: &amp;nbsp;&amp;nbsp;it is &lt;U&gt;YOUR &amp;nbsp;&amp;nbsp;RIGHT&lt;/U&gt;.
