Question 69529
i have some doubt abt ur question.  is it 2xx4y=8?  or 2x4y =8? Did  u put second  x to denote x or multiplication notation?
 ok, look at the solutions   2x4y=8
                            or 8xy=8
                            or  xy =1
                            or  x=1/y
          if y=1  then x=1;   if y=2 ,x= 1/2; if y=3  ,x=1/3


              if it is   2xx4y=8
               or       8xxy=8
               or       xx=1/y
             if y=1  x=+1 or  -1   
             if y=4  x=1/2  or -1/2
