You can put this solution on YOUR website!
the expression is:

(-9a-5b/9a) + (6a+8b/3a ) -4

remove the parentheses to get:

-9a - 5b/9a + 6a + 8b/3a - 4

-9a + 6a is equal to -3a.

-5b/9a + 8b/3a is equal to -5b/9a + 24b/9a which is equal to 19b/9a.

you final expression should be -3a + 19b/3a - 4

you got 9a + 19b/9a - 4

not sure what you did to get 9a.

otherwise it looks like you did ok.
