Divide  the first  equation through by   -4  and we get that

 

x + y  = 0   which implies  that   y  = -x

 

Sub this into  the second equation  for  y   and we have that

 

-5x  - 3 (-x)  = -6

 

-5x  + 3x =  -6

 

-2x  = -6   divide both sides  by  -2

 

x  = 3  

 

And  

 

y =  -x  =  -3
