Question

x-y/xy - 9-y/9y

Answer 1

\[\frac{ x-y(9y) }{ xy(9y) }-\frac{ 9-y(xy) }{ 9y(xy) }\]

Answer 2

\[\frac{ 9xy-9y ^{2} }{ 9xy ^{2} }-\frac{ 9xy-xy ^{2} }{ 9xy ^{2}}\]

Answer 3

\[\frac{ 9y ^{2}-xy ^{2}+9xy-9xy }{ 9xy ^{2} }\]\[\frac{ 9y ^{2}-xy ^{2} }{ 9xy ^{2} }\]
\[\frac{ 9y ^{2}-1 }{ 9 }\] I think you might be able to take it one more step and make it\[y ^{2}-1\]

Answer 4

how did you get \[\frac{ x-9 }{ 9x }?\]

Answer 5

im not sure but i get it now thanks :)

Answer 6

yup
