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

(x-3/20 ) * 120>= (x-4/24+1/120)*120

6x-18 >=5x-20+1

putting like term together

6x-5x >=18-20+1

x>=-1

in interval notation

-1 U infinity

To show on number line just put a small circle on -1 and shade it fully, and then create an arrow from that point , pointing towards infinity(positive numbers)

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