-------------
Put the 1st one in slope-intercept form
-5x+3y=-5
3y = 5x - 5
y = (5/3)x - 5/3
----
Both slopes are 5/3 --> parallel lines, no intersection, inconsistent system.
No solution.

......eq.1
......eq.2
___________________________substitute from eq.2 in eq.1
......eq.1....solve for
.......no solution exist, lines have no intersection point
if you write both eq. in slope-intercept form where and , you will have
......eq.1
......eq.2
as you can see, slopes are same, both lines have and it means lines are parallel
