Thank you for the opportunity to help you with your question!

Multiply the first equation by 2 you get 6x+12y=36

Multiply now the second one by (-3) you get -6x-12y=18

Sum these 2 equations you get 0=54 which is impossible so NO SOLUTION

Please let me know if you need any clarification. I'm always happy to answer your questions.
