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
