anonymous · Answer

EXAMPLE

2x - 3 = 2
                          SINCE YOU WANT TO KEEP VARIABLE ON ONE SIDE
2x   -   4 =    2    ADD THE ADDITIVE INVERSE   4         ( OR OPPOSITE )  
          +4    +4            
           -------  
 2X  =   6     
 
                              YOU WANT TO SINGLE IT TO 1
  1/2   [ 2X = 6  ]          MULTIPLY IT BY THE RECIPROCAL   1/2            
              X =   3
