Answer:

xy1

Step-by-step explanation:

Correct option is C)

Given two equations are 2x+y+4=0 and x=3y+7=0

let us consider 2 equations ax+by+c=0 and mx+ny+p=0

By cross multiplication method ,the equations obtained will be ,

b×p−n×c

x

​

=

c×m−a×p

y

​

=

a×n−b×m

1

​

Thus comparing it with given 2 equations we obtain:

7−12

x

​

=  

4−14

y

​

=  

6−1
