How do you solve the following system?: #-6x -3y =1, -2x +4y = -5#
We have the equations:
I would say the best way to procede is to eliminate the
That means the 2nd equation becomes:
Now subtract the equations from each other to eliminate the
Now put this value of
Hence our final solution. It is good practice to put these values into the other equation to check that they work.
