Question

2x-4y=6 x-2y=3 substitution

Answer 1

are we trying to solve for both x and y? and do we have any given values?

Answer 2

2x-4y=6

lets take 2 common from both the sides
=> 2 ( x -2y) = 2(3)
=> x - 2y = 3

and the other equation that we have is
x-2y=3

since the equations are equal
It implies they lie on the same line
and hence infinite number of solutions exist
