Start with the second equation.


Rearrange the terms.


So we have the 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 and y 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.
