The original equation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=e1f57b79f6a4da57c7f4dc5d593d8622.png\")
and value of x is -2.
To check the solution of the equation, substitute the value of x=-2 in the original equation.

The original equation is ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=e1f57b79f6a4da57c7f4dc5d593d8622.png\")
and value of x is 1.
To check the solution of the equation, substitute the value of x=1 in the original equation.
