#x# has no value. #x# is undefined.

Remove the brackets to get.

#-9x +2 =-9x+6#

If you look at this carefully you will realise that there is a problem even before we start solving the equation...

There is no way that we can do 2 different things to the term -9x and have the answers equal!

Let's solve and see what the numbers tell us.

#-9x+9x = 6-2#

#0 = 4#

This is clearly false! And there is no #x#?

This is an indication that the equation cannot be solved. There is no value of #x# which will make the equation true.
