Answer:

Step-by-step explanation:

17 X  + 12 Y   =   68                     ........ eq(i)

12 X +  17 Y    =   48                   .........eq. (ii)

eq .(i)  -  eq.(ii)

17X + 12Y - ( 12X + 17Y )  =  68 - 48

17X - 12X  + 12Y - 17Y     =  20

                      5X - 5Y    =  20

                    5( X - Y )    =   20

                       X - Y       =   20 / 5

                       X - Y     =    4

the value of X - Y  is  4
