a+b+ab=35 => ab+a+b+1=35+1=36 => (a+1)(b+1)=36. a and b have to be positive whole numbers, so you need two numbers x and y so that x*y=36, x and y distinct and neither can be 1. There are multiple options.
Solving these kinds of equations is not always easy because it's not necessarily got one answer that you can just find with normal algebra. It's also kind of hard to give proper hints without displaying most of the methods.
One way is to exhaust the options for b and find a corresponding answer for a. A hint with this method is that if you plug (5,5) into the expression a+b+ab you get 35. However this isn’t a solution to my question as a is not strictly bigger than b. However, this does mean that b<5, as if b>5, a>5 which means the expression is bigger than 35, and using (5,5) gives 35 as shown before.
Another is to rearrange the equation into a form where you can factorise it. If you want help with this second way feel free to ask.
Harry Potter is one of my favorite book series. What are your favorite books to read? And by what author? I also like the movies about Harry Potter and his friends at Hogwarts.
My grandparents get on my nerves so bad. My grandma is evil, greedy and selfish. She takes half my grandpa's money which me and my mom need for food, medicine, supplies and other requirements for our daily lives.
I had a wonderful holiday Chris, thanks for asking. We sat near the fireplace and read some books and ate some cake. It was cold some nights, we had to bundle up under the blankets.
Well, did everyone have an enjoyable, relaxing Christmas this year? We certainly did, me and my mother. We played some board games and ate some Christmas cookies.
Oh, I missed it: e^i music is in base 12, the real-part as acoustic piano, and the imaginary-part as marimba / harp. I'm making a build app project (while learning Java) and I'm using this self-composed song as bg music
Yes, I had a great weekend, we got 3-4 inches of rain and had an isolated tornado. Luckily it didn't do too much damage, just knocked the power out for an hour.
Are you doing good John, we are going to a pumpkin festival Saturday. It will be from 11am to 7pm, there will be all kinds of fun activities and games for all different families around the world.
Is everyone ready for Halloween? Get your costumes, movies and candy ready for some spooky fun. However in Iceland, we only do trick or treating after certain hours, we don't do it very late at night.
I hope it's not the end of BL soon, but there's been some strange things going on with it, idk if the database is corrupted now or the technology is so outdated. But someone needs to investigate it/take a look.
suhangha is a complete genius in terms of levels. Some of his levels just look like they are trivial but they never are. Other levels of his are incredibly well crafted but still extremely difficult.
Your levels so far seem relatively good in my opinion. Some of them can be a bit mindless from memory but I havent found one of those from you in a while. However there are always areas for improvement.
