Question

Which of the following is a solution for the given linear equations in two variables x+2y 8 0:​

Answer 1

Step-by-step

x+2y=8

And 2x+4y=16

These given equations are in the form:

a1x+b1y+c1=0 and 

a2x+b2y+c2=0

Where

a1=1,b1=2 and c1=8 

a2=2,b2=4 and c2=16

a2a1=21,b2b1=42=21

As we know, the condition for the equations to have infinitely many solutions is

a2a1=b2<
