Given:
A figure.
and 
To find:
What kind of figure and the value of x
Solution:
All four sides are congruent.
Diagonals bisect each other.
There the given figure is rhombus.
Diagonals bisect the angles.
⇒ 
Subtract 3 on both sides.
Subtract 6x from both sides.
Divide by 3 on both sides.
The value of x is 
.
