Question 126068: solve the system by addition method. if unique solutions doesn't exist, state whether the system is inconsistent or dependent.
12x-15y=-33
-4x+5y=11 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 12x-15y=-33
-4x+5y=11
---------------
Multiply thru the 2nd equation by -3 and you
will see that the system is dependent.
Multiplying you get:
12x-15y = -33 which is the same as the 1st equation.
