sorry. it is 60/x-60/(x-4)=9/x

Is it 60/x - 60/(x-4) = 9/x ???
If so.....
common denominator of x(x-4)
[ 60(x-4) - (60x) ] / (x(x-4)) = 9(x-4) / (x(x-4))
multiply everything by x(x-4) to get rid of fractions
(60x - 240 - 60x) = 9x - 36
-240 = 9x - 36
-204 = 9x
x = -204/9 = -68/3

60 / x - 60 / (x - 4) = 9 / x
60.(x - 4) - 60 x = 9 (x - 4)
60x - 240 - 60 x = 9x - 36
9x - 36 = - 240
9x = - 204
x = - 204 / 9
x = - 68 /3

60/x-60/x-4=9/x
-4=9/x
-4x=9
x = -9/4

60/x-60/(x-4)=9/x /* x(x-4)
60(x-4)-60x=9(x-4)
60x-240-60x=9x-36
-9x=-36+240
-9x=204
9x=-204
x=-204/9=-68/3
