Question

1/2 (x-3)=1/2 + (x-3)

Answer 1

                 
                 1/2 (x-3) = 1/2 + (x-3)
                  x/2 - 3/2 = 1/2 + x - 3                 
                  x/2 - 3/2 - 1/2 + 3 = x                 
                  x/2 - 4/2 + 3 = x                 
                  x/2 - 2  + 3  = x                 
                  x/2 + 1 = x -----mmc=2                 
                    x  +  2  = 2x                         
                            2  = 2x - x                         
                            2  =  x

              Resposta:  x = 2
