y=3x
The answer can either be no solution or infinitely many solutions, please explain your work Answer by arden42(16) (Show Source):
You can put this solution on YOUR website! If and then substituting the second equation into the first gives us:
This is now simple to solve for x:
We can now substitute this value into either of the first equations to get the value of y (I'll use the first):
Result: , . Graphically, this means that the 2 lines intersect at (2,6), as can be seen if we put them onto a graph:
(
