Answer:

Correct option is

A

11

−4

and

11

−10

x+4y=−4 ------- (1)

2x−3y=2 ------ (2)

From equation 1:

4y=−4−x

y=

4

−4−x

Substitute the value of y in equation 2:

2x−3y=2

2x−3(

4

−4−x

)=2

8x+12+3x=8

11x=812

11x=−4

x=

11

−4

Now, Substitute x=

11

−4

in equation 1:

x+4y=−4

11

−4

+4y=−4

−4+44y=−44

44y=−44+4

44y=−40

y=

44

−40

=

11

−10

Therefore the solution is: x=

11

−4

and y=

11

−10
