No solution
-4x + 2y = -16
-8x + 8y = 8
(-4x*2) + (2y*2) = -16*2 becomes -8x + 4y = -32.
(-8x + 4y = -32) compare (-8x + 8y = 8).
4. We can see that both equations have the same "-8x" term, but the "y" terms and the constants on the right side of the equations don't match. This means that there are no values for x and y that would make both equations true at the same time.
So, there's no solution for this system of equations. It's called an inconsistent system.
