Let's solve the system of equations:
2x−4y=−6
−4y+4y=−8
For the second equation,
−4y+4y cancels out, and you are left with
0=−8, which is not a true statement. This means that the system of equations is inconsistent, and there is no solution.
So, the system is inconsistent, and there is no solution for
x and y that satisfies both equations simultaneously.
