6193 - [ 72 . ( x - 104 ) + 98 ] = 5807
72 . ( x - 104 ) + 98 = 6193 - 5807
72 . ( x - 104 ) + 98 = 386
72 . ( x - 104 ) = 386 - 98
72 . ( x - 104 ) = 288
x - 104 = 72 . 288
x - 104 = 20736
x = 20736 + 104
x = 20840
6193-[72.(x-104)+98]=5807
72.(x-104)+98=6193-5807
72.(x-104)+98=386
72.(x-104)=386-98
72.(x-104)=288
x-104=288.72
x-104=20736
x=20736+104
