Start with the first equation.


Multiply both sides by the LCD 12


Distribute and multiply


So we now have the system of equations:






Now add the equations together. In order to add 2 equations, group like terms and combine them



Combine like terms and simplify



Notice how the y terms cancel out




Simplify


Divide both sides by to isolate x


Reduce



Now plug this answer into the top equation to solve for y

Start with the first equation


Plug in


Multiply


Subtract from both sides.


Combine like terms on the right side.


Divide both sides by to isolate .


Reduce.


So our answer is
and
