Answer:

x = - 1 ;  y =0

Step-by-step explanation:

     −10y+9x= −9    --------------> EQU 1

       10y+5x= −5 ​    --------------> EQU 2

____________________

       0 + 14x = -14                     { add EQU 1 and EQU 2 }

                  x = -14/14

                   x = -1

Substitute the value of x in EQU 1;

-10y + 9 *(-1) = -9

-10y - 9  = -9

        -10y = -9 +9 = 0

             y = 0
