The correct option is D x=−2 and y=−3
5x+y=−13 -------------(1)
3x−2y=0-------------(2)
D=∣∣∣513−2∣∣∣
=(5)×(−2)−3×(1)
=−10−3
=−13
Dx=∣∣∣−1310−2∣∣∣
=(−13)×(−2)−(0)×(1)
=26−0
=26
Now,
Dy=∣∣∣5−1330∣∣∣
=(5)×(0)−(3)×(−13)
=0+39
=39
Again,
x=(Dx)D and y=(Dy)D
So, x=(26)−13=−2
and
y=(39)−13=−3
Hence,
x=−2 and y=−3
