We multiply the first equation by – 3, and add it to the second equation. − 3 x − 9 y = − 21 3 x + 4 y = 11 − 5 y = − 10. By doing this we transformed our original system into an equivalent system: x + 3 y = 7 − 5 y = − 10. We divide the second equation by – 5, and we get the next equivalent system.
