Start with 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.


Simplify.


Divide both sides by to isolate .


------------------------------------------------------------------


Now go back to the first equation.


Plug in .


Multiply.


Multiply both sides by the LCD to clear any fractions.


Distribute and multiply.


Add to both sides.


Combine like terms on the right side.


Divide both sides by to isolate .


So the solutions are and .


Which form the ordered pair .


This means that the system is consistent and independent.
