Answer:
X=11 and y=2 is the correct answer
Step-by-step explanation:
x+2y/3=-1
X+2y=-3 is the first equation
and
x-y/3=3
x-y=9 is the second equation
now,by subtracting eq. first from second equation
x-y=9
X+2y=-3
now we will change sign in the second equation
so, -3y=-6
and y=2
and, x-2=9
so,X=11 And y=2
