Add and subtract the rational expressions as indicated. Be sure to express your answer in simplest form
((9)/(7x)) + ((1)/(2y)) -1
I got an aswer of (16y)/(7x+2y+1)) but when I submit it shows me as wrong. Can anyone help, thanks

9/(7x) + 1/(2y) - 1
has a common denominator of 14xy
so ...
= (18y + 7x - 14xy)/(14xy)
(Did you really ADD the denominators???)
