EW is correct...a literal equation usually involves several variables....we are not trying to find a numerical answer...rather....we are using the equation to (usually) solve for a variable

 

A.  not an equation

B. We can find a numerical  value for x....so...not literal

C. this is an identity

 

D is literal.....we can use it to  solve for either x or y

 

cool cool cool
