Step-by-step explanation:

[tex]\frac{1}{4}x - 5 = \frac{3}{4} x - 12[/tex]                            Multiply all terms by 4  

-3/4x      = -3/4x                                  x - 20 =  3x - 48

-2/4x - 5 = -12                                     -x        =  -x          

-2/4x  - 5 = -12                                        -20  =   2x  - 48  

          +5  = +5                                       +48  =          +48  

   -2/4x =   -7                                             28  =    2x

   -1/2x = -7                                                28/2  = x    

     x = -7 ÷ -1/2                                           14    = x  

     x =  14
