Question 93739
Solve by substitution:
{{{8x-4y = 16}}}
{{{y = 2x-4}}} Substitute this value of y into the first equation and solve for x.
{{{8x -4(2x-4) = 16}}} Simplify.
{{{8x-8x+16 = 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".
