Answer 2

Answer:

X=4➖2y

Step-by-step explanation:

We have two equations ,

X➕2y ➖4=0

2X➕4y ➖12=0

By using substitution method

from Eq.1 we get

X= 4➖2y

substitute the value of x in equation 2

2X➕4y=12

2(4➖2y)➕4y=12

8➖4y➕4y = 12

8➖0=12

Hence , this shows that this equation does not have any solution because they form parallel line

X=4➖2y
