Solve by substitution:
8x-4y+=+16
y+=+2x-4 Substitute this value of y into the first equation and solve for x.
8x+-4%282x-4%29+=+16 Simplify.
8x-8x%2B16+=+16 Combine like-terms.
16+=+16
This result indicates that the two equations represent the very same line and there are an infinity of solutions.
The system is a "consistent system" and the equations are "dependent equations".
