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

Let's note 1 the first equation and 2 the second one. 

1+2 provide 6x=36 so x=6 

you replace in the first equation : 6-3y=-6 <=> 3y=12 <=> y=4 

So x=6 and y=4 

Good Luck

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