Answer
The two equations/lines $coincide$ (overlap). Infinite solutions.
Work Step by Step
We use the addition method below:
We add the two equations:
$\frac{1}{4}x-\frac{2}{5}y=1$
$5x-8y=20$
Multiply both sides of the first equation by $-20$ to cancel $x$.
$-5x+8y=-20$
$\underline{+5x-8y=+20}$
$0=0$
This is a true statement, which means we have infinite solutions.
So the two equations/lines coincide (overlap).
