A very simple question.(adsbygoogle = window.adsbygoogle || []).push({});

If I have, for simplify, two equations that describes lines:

2x + 3y + 4 = 0

3x + 2y + 5 = 0

adding them side-by-side we get: 5x + 5y + 9 = 0

The question is: what happens if I add these two equations side-by-side? What's the meaning, what happens geometrically when I add these two equations?

Thank you
