The system is inconsistent.

Explanation:

Assuming that the equations are:

$5x-2y=3$
$-20x+8y=6$

Write the lines in slope intercept form of: $y=mx+b$ , where m is the slope and b is the y-intercept:

$2y=5x-3$
$8y=20x+6$

$y=(5/2)x-3/2$
$y=(5/2)x+3/4$

Notice that the lines have the same slope but different y-intercepts, therfore the 2 lines are parallel, they do not intersect so this system has no solution. Hence the system is inconsistent.
