Answer:
x=-3
y=1
Step-by-step explanation:
x+y=-2...(1)
2x-3y=-9...(2)
In equation (1) make x the subject of formula by subtracting y from both sides
x=-2-y...(3)
Substitute (3) into (2)
2(-2-y)-3y=-9
Open the bracket
-4-2y-3y=-9
Collect like terms
-2y-3y=-9+4
-5y=-5
Divide both sides by-5
y=1
Substitute y=1 into(3)
x=-2-1
x=-3
Therefore,x=-3,y=1
