Step-by-step explanation:


To solve this system of equation, let's multiply the second equation by two so both equations have a
:


Next, let's add the two equations together to remove the
and solve for
:



Now that we have the value of
, we can plug it into either of the equations to solve for
:




or




Therefore, the solution to this system of equations is
.
