<PRE><B>Question 357218</B>
We know by definition that a rhombus is a quadrilateral that has 4 equal sides. &lt;br&gt;

A rhombus looks like a diamond, and is basically a smushed square.  Every square is a rhombus, but not every rhombus is a square.&lt;br&gt;

So if we know that the sides are equal, we know:&lt;br&gt;

{{{5x+7=6x-1}}}&lt;br&gt;

{{{x=8}}}&lt;br&gt;

&lt;b&gt;Thus, the value for x is 8.&lt;/b&gt;&lt;br&gt;

This means that each side of this rhombus is 47 units in length.&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
