Could REALLY use some help with a math problem.....

[ryshy]

i cant copy/paste it cus its online hw and theyre smarter than that, but ill try my best to type it out

2/x+18 - 3/x-18=5x/x^2-324

Ive tryed this "type" of problem (linear/rational equations) about 5 times and i figured out a way to guess the answer jus by looking at the problem and thinking about number associations, but thats very shoddy and is resulting in a bad grade.

Can someone PLEASE explain this to me, just knowing how to do this will probably help me know how to do all of them. And ive watched videos but they always require some prerequisite math knowledge so i dont really understand them.

plz?

Put some brackets in to separate the terms so I know what I'm dealing with and I could solve that easily.

Handwrite it and take a picture so we can see it, cuz as of now, I'm seeing 7/(324) as the answer.

It looks simple, but I can't process it written in one line like that. If it's online post a screen shot

lets do math..

2/x+18 - 3/x-18=5x/x^2-324

first of all this equation is solved using the process of commulative and the destributive property..

so youll devide each number by 3.557 which will give you a decimal of 13.67 on each number..

now devide the perihelion times by 16% and square it to the sixth domixition...

that will give you a simplified answer of : 2/8 = 13.689999e

Yeah, definitely going to need a screenshot, parentheses or something. For example, the first part could easily be interpreted as (2/x)+18 or as 2/(x+18)

breh just put it into wolfram alpha:

That's really helpful when it's test time.

2/x+18 - 3/x-18=5x/x^2-324

2 -
x + 18

3 =
x - 18

5x_____
(x + 18)(x - 18)

Don't know why it spaces it funny if its on one line

2(x - 18) - 3(x + 18) = 5x

Solve from there

thank you @Colicat ! bingo... give her a hand in right direction. don't silver spoon her to answer.
