Question

x-3y =3
and 31-gy
x-gy=2 by elemination method​

Answer 1

Step-by-step explanation:

Given equations are

3x+2y=0 ....(1)

and x+3y=7 ....(2)

Therefore, 3x=−2y⇒x=

3

−2y

....(3)

On substituting this value in equation (2), we get

3

−2y

+3y=7

⇒−2y+9y=21

⇒7y=21

⇒y=3

Put this value in equation (3),

x=

3

−2×3

⇒x=−2

Therefore, the solution is x=−2,y=3.
