Question

x+2y=0 , 2x+y+6=0
By elimination method​

Answer 1

Answer:

Given, equations are

2x+y=6 ....(1)

and x−2y=−2 .....(2)

Multiply 2 with equation (1), we get

4x+2y=12 ....(3)

Add equations (2) and 3,

5x=10

⇒x=2

Now, put this value in equation (1),

2(2)+y=6

⇒4+y=6

⇒y=2

Therefore, the solution is x=2,y=2.
