How do you solve the system of equations #-6x + 5y = - 5# and #10x - 10y = 20#?
For this system of equations, I would adjust the first equation so that when you add the two equations together, the
You can do so by multiplying everything by
Now that this equation has a positive
You can now solve for
Now you can take any of the equations and enter in
Divide both sides by
There are many ways to solve systems of equations, but often it's easiest to find a way to adjust one of the equations so that when you add them together they eliminate one of the variables.
