The original equation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=de61520c17a2660302c03cd6abc01aa0.png\")
and value of x is 2/5.
To check the solution of the equation, substitute the value of x=2/5 in the original equation.

.
The above statement is false, so x=2/5 is a not solution of the original equation.
