______________________________________________

Explanation:
________________________________________________
2x - 1 + 3x = 180 ;

Combine the "like terms" on the left-hand side of the equation:
________________________________________________
   +2x  + 3x = + 5x ;
_____________________________________
 And rewrite:
_____________________________________
   5x - 1 = 180 ;
_____________________________________
  Add "1" to each side of the equation:
_____________________________________
   5x - 1 + 1 = 180 + 1 ;
_____________________________________
     5x = 181 ;  
_____________________________________
  Divide EACH SIDE of the equation by "5" ;
_____________________________________
     5x / 5 = 181 / 5 ;
_____________________________________
   to get:
_____________________________________
  x = 36.2  .
