Start with the second equation.

Rearrange the terms.

So we have the given system of equations:

Add the equations together. You can do this by simply adding the two left sides and the two right sides separately like this:

Group like terms.

Combine like terms. Notice how the x terms cancel out.

Simplify.

Since is always true, this means that there are an infinite number of solutions. So the system is consistent and dependent.
