Answer:

(x, y) = (-2 12/17, -51)

Explanation:

Here is the answer to ...

`4x+(9)/(y)+11=0\\\\(6)/(y)-3x=8`

If you mean something else, then parentheses are needed.

Let z = 1/y. Then the equations in general form are ...

`4x+9z+11=0\\3x-6z+8=0`

The solution (cross multiplication method) is ...

x = (9·8 -(-6)·11)/(4(-6)-3·9) = 138/-51 = -2 12/17

z = (11·3 -8·4)/-51 = -1/51

y = 1/z = -51

The solution is (x, y) = (-2 12/17, -51).
