two equations have no solution and if you graphed them their lines would not intersect, they would be parallel
Explanation:
we can substitute the value of 'y' which is '2x' into the second equation as follows:
-6x + 3(2x) = 16
-6x + 6x = 16
0
16
therefore, these two equations have no solution and if you graphed them their lines would not intersect, they would be parallel
