Answer:
   (x, y) = (-2 12/17, -51)
Step-by-step explanation:
Here is the answer to ...
   
If you mean something else, then parentheses are needed.
__
Let z = 1/y. Then the equations in general form are ...
   
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).
