Start with the given system of equations:
Multiply the both sides of the second equation by 2.
Distribute and multiply.
So we have the new system of equations:
Now 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.
Simplify.
Since is ALWAYS true, this means that there are an infinite number of solutions.
So the system is consistent and dependent.
