#x=12#

Explanation:

#2x-6=18#

  1. Isolate the variable term.
    #2x\cancel{-6}\cancel{\color{indianred}{+6}}=18\color{indianred}{+6}# simplify...
    #2x=24#
  2. Get the variable alone to solve for it.
    #(\cancel(2)x)/(\cancel(\color(seagreen)(2)))=24/\color(seagreen)(2)# simplify...
    #x=12#
