Hi, can you help me with a math problem kbin? It's algebra, and it's been a long time since I've had to do it. Can you explain to me how simplifying the terms comes out to 9/2 in the pictured equation

@nyarlathotep thank you so much! There's other comments to read below, but this is the first one that has triggered my memory for common denominators. You've explained it brilliantly!
Edit: can you explain how the reciprocal works and comes out to 2/9? Been a long time since high school
I think the first one was "mods are asleep, post beans" or something on lemmyshitpost
