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

5x-100 and x-20 are supplementary so 6x-120=180, thus x=(120+180)/6=50°

Also 3y=x-20=50-20=30 finally y=30/3=10°

You can verifu that y+140 and x-20 are supplementary :

y+140+x-20=10+140+50-20=180° 

Hope it helps !!!

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