To solve the system of equations using elimination, we can follow these steps:

1. Multiply the first equation by 3 to make the coefficients of x in both equations equal:


2. Add the two equations together to eliminate x:



3. Solve for y:


4. Substitute the value of y into one of the original equations to solve for x:





Therefore, the solution to the system of equations is
and
