Hi there.   :)  Each of those equations in the original system of equations represent lines.  When you go through the linear combination method to find a solution to a system of equations and the end result is something that is never true, such as 0=-12, that means that there is no solution to the system of equations and that the lines are parallel.  So the answer to this question would be the first option.

Option 2 is invalid because if the two equations were just different forms of the same line, there would be an infinite number of solutions.

Option 3 is invalid because parallel lines can not intersect, and therefore the system of equations can have no solution.

Option 4 would only occur if you used the linear combination method and the end result was something that was always true, such as  0=0  or  5=5  etc.  We know this isn't the case because we ended up with 0=-12
