1/x + 1/y = y/(xy) + x/(xy) = (x+y)/(xy)

Multiply 1/x by y/y to get y/xy then multiply 1/y by x/x to get x/xy. Now you have a common denom and you can simply add the numerators and keep the denom as it is. So your answer should by (x+y)/xy

the common denominator is xy.
On 1/x, divide xy by x (denominator) and multiply by 1= y/xy
On 1/y, divide xy by y (denominator) and multiply by 1= x/xy
so, y/xy + x/xy = (x+y)/xy

1/x + 1/y = 0
1/x = - 1/y
x = -1/y
or
1/y = -1/x
y = -1/x

Common denominator for x and y is xy
y / xy + x / xy
(y + x) / xy
