lol computers are not as clever as people they often make mistakes due to the sickness they have i mean viruses

jhonyy9 (jhonyy9):

yes you can getting the answer 3x+6/7x if you write your equation in the form (x+1)/x - (4x+1)/7x --- because with (-)(4x+1) will result to you -4x-1 and hence will be (7x+7-4x-1)/7x =3x+6/7x

jhonyy9 (jhonyy9):

i have checked it newly and yes you can get the result 3x-6/7x if you write your equation in the form (x-1)/x -(4x-1)/7x
