9x-2y = -3,  - 3x+5y=27

Note that if we multiply the second equation by 3, we have

-9x + 15y = 81

So now we have

9x  -  2y   = -3

- 9x + 15y = 81          add  these  and we have

13y  =  78             divide both sides by 13

y =  6

And to find x we can use

9x - 2(6)  = -3

9x -  12  = -3    add 12 to both sides

9x  =  9         divide both sides by 9

x =  1

So....the answer is (x,y) = (1, 6 )
