(y+1)/2 = -8x

Please solve for y, show all steps.

I'm sorry, we don't do people's homework here.

You cannot solve for y but only make y the subject of formula.

I'll start;

multiply everything by 2 to get rid of the fraction:





Can you continue it now? You have to remove that 1 from the y. But if you do so, you have to do the same with -16x. Post your answer. :)

This is obvious that this was someone's homework assignment.

I know CM =/, I just did the first step, to show that's it's not difficult at all. No big deal.

I have a packet of 50 questions, there are a few difficult ones, which I needed help. That is why I asked.

Regardless, we don't do people's homework here. We can help you figure it out, but we're not going to give you answers.

Mokay, but be sure to post what your tried first, where you are stuck.

[If 1994 is your birth year, then you are two years younger than me, and I could already do those kinds of problem. I wonder how your educational system works. I'm clearly behind others in Australia, China, and the USA... but if you are in the US, then, I'm all confused... =/]

That's fine, he didn't give me the answer. I solved it anyway.

Im going to 9th grade in the U.S.

LOL, I'm even more confused with those 'grades' :p. Never mind that. Next time you ask, be sure to show clearly why you have problems, OK? :)

I think there's some confusion in that. I can't speak for the other countries or what anyone else said, but I know when I made the comment I did, it was when you were posting questions that I thought were pretty easy for what you said was 11th & 12th grade. And they were. But they've gotten more difficult, so the comment kind of doesn't count.

I also saw elsewhere when you said 11 & 12 yo, as in years old? That's not the same as 11th and 12th grade. 11 & 12 yo would be pretty darn young for that stuff you were posting.

As for the problem posted here, not positive but I suspect I learned that kind of thing around 9th grade also. I had an introduction to algebra at the end of 8th grade, but my first real algebra class was 9th grade. 10th was plane geometry. 11th was harder algebra and trig. 12th I had some analytic geometry and intro calculus. Some schools do start algebra sooner. Some people never take it or learn it.

I know they are not the same... I said in the other post you're referring to that the questions were for 11 and 12 years old, and here, if the OP is really 15, then the grade does not matter that much; I'm comparing only the years.
