inconsistent

Step-by-step explanation:

x - 2y = 5

=> x - 2y - 5 = 0.....(1)

2x - 4y = 1

=> 2x - 4y - 1 = 0.....(2)

In the standard form of linear equation of two variables, here -

a_{1} = 1 \: . \: b_{1} =  - 2 \: . \: c_{1} =  - 5 \\ a_{2} = 2 \: . \: b_{2} =  - 4 \: . \: c_{2} =  - 1

So,

 \frac{a_{1}}{a_{2}} =  \frac{1}{2}  \\  \frac{b_{1}}{b_{2}} =  \frac{ - 2}{ - 4}  =  \frac{1}{2}  \\  \frac{c_{1}}{c_{2}} =  \frac{ - 5}{ - 1}

 =  >   \frac{a_{1}}{a_{2}} =  \frac{b_{1}}{b_{2}} \neq \frac{c_{1}}{c_{2}} \\

So,

there will be no zero for this pair of equation.

And The pairs are inconsistent.

Hope it helps.
