Answer:

4x-y=8.......(1)

2x-3y+6=0

2x-3y= -6......(2)

दुसरे समीकरण को 2 से गुणे.

4x-6y= -12.....(3)

समीकरण 1 और 3 की वजाबाकी करे

4x- y = 8

4x-6y= -12

---------------------

0-7y=21

-y=21

----

7

-y=3

y= -3

y=-3 इस किमत को समीकरण दो में डालेगे.

2x-3y= -6

2x-3(-3)= -6

2x+9= -6

2x=-6-9

2x=15

x= 15

-----

2

x =7.5

इसलिये (x, y)=(7.5, -3)
