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)
