You said that                                | x/2 | + 3  =  9 and 1/4

Subtract  3  from each side:         | x/2 |        =  6 and 1/4

Multiply each side by  2 :              | x |          =  12 and 1/2

That last statement is true if          x = (12 1/2)
                                                  or
                                                      x = -(12 1/2)

so those are both solutions of the original equation.
