what does this mean? x E R

Answer provided by our tutors

It means that "x is an element of every real number", so any numeric value for 'x' would be valid for the equation. 

It is always helpful to use the 'Options' tab and begin a solution with 'a few steps', then increase the number of solution steps when the additional steps are helpful rather than overwhelming and/or confusing.
