If you have yx-x=3y+2, how would you solve for x?
My book says you can divide by y-1, but why would that give you x on the left if it's yx-x, it's not yx-1??

I'm trying to find articles specific to this question, but I don't find what I'm looking for. Need to know exactly how sodium hydroxide and sodium chloride will kill or inhibit bacteria and fungi. I'm sure this info must be out there somewhere because NaOH is the base of many detergents that is used in the food industry.
Give references please.

I have a really big problem, I'm not sure if I'm bad or good in math, I usually get good grades in it, the problem is, now I'm in an advanced level, and it's getting really hard, I don't understand the explanation of the teacher nor the book, I can't afford a tutor, my mom can't help since she doesn't know much, my dad knows everything but he doesn't want to help, that's out of the question. I don't know what to do. I don't wanna fail or get a bad grade. I'm all in tears right now, I'm running out of time, and it's getting worse every second. How am I gonna continue? I keep on telling myself I'll understand, but I keep onreading and it's just a waste of time, what am I going to do?

I know it must vary with the size of the person, but is there a way to guess. Like the way you can guess the size of your heart, because it's about the same size as your fist?

How can choice exist? Every action leads to a consequence, according to the laws of nature, the laws of science. Given that our brain is nothing more than a biological machine, processing information how it is programmed to do by nature and nurture, where does choice fit in?

Think about it, our nuture is based on our parents nurture. If you go back enough generations, the nurture would be purely based on nature (consider algae). So, every choice we think we make is just the result of our programming, based on the hardwiring of our brain? If there is no choice, there is no guilt, blame or consequence!

On the other hand, if you believe in choice you cannot believe the normal laws of science describe every aspect of the universe. Mind you, choice is an illusion and you may believe it because you are programmed to 'chose' to believe it.

I see no way an Atheist can believe in choice. Can anyone elaborate on this for me?
