Remember when you followed your notes earlier and worked out the x and y solution to a system of 2 equations?

This is the same idea.

campbell_st · Answer

these are a pair of parallel lines... so have no solution

 y = 1 - 3x

2y = -9 - 6x           or  y = -9/2 - 3x

so they don't intersect.

Ok, good point.  So, if you had tried to solve it as a system like you did earlier, you would end up with something that didn't make sense, like 3 = 6 or whatever... meaning, no solution.

The other approach as shown above is to put both lines into a form where you can see the slope... then you realize they have the same slope, so they are parallel.

A solution to a system of equations, if there is one, is the point where the two equations intersect.  Since parallel lines NEVER intersect, there is no solution on this problem.

Does that make sense, @pinkmommy ?

yes, sorry i didnt respond earlier, i was busy with my baby but yeah. thank you both for your help.  :)

anonymous · Answer

Not a problem :)  I was guessing you had other immediate priorities :)
