x=-3, y=1

Step-by-step explanation:

Given equations are:

2x-3y=-9 Eqn 1

x+y = - 2 Eqn 2

From eqn 2:

$x=-y-2$

Putting x=-y-2 in eqn 1

$2(-y-2)-3y=-9\n-2y+4-3y=-9\n-5y-4=-9\nAdding\ 4\ on\ both\ sides\n-5y-4+4=-9+4\n-5y=-5\nDividing\ both\ sides\ by\ -5(-5y)/(-5)=(-5)/(-5)\ny=1\nPutting\ y=1\ in\ eqn\ 2\nx+1=-2\nSubtracting\ 1\ from\ both\ sides\nx+1-1=-2-1\nx=-3$

Hence,

x=-3, y=1
