3x  2y+ -6 and 3x + 2y +-12 

is the parallel lines system equation has no solution ? explain 


Sagot :

the graphs of the two equations are parallel to each other
therefore there is no solution
note that the x & y in the two equations are multiply of each other
if you try to solve it by elimination method, you will find the x & y
cancelled each other out
you will have      0x+0y = constant
