Will someone help me with some math problems?

[rebgirl420]

Ill give rep to whoever can help. Im terrible in math and these problems are giving me a hard time.

2 (x + 4) - 5 (x - 3) = 32

and

3 x - 8 (3 - x) = 53

first one is x = -3
second one is x = 7

woops heres how u do it:
2x + 8 - 5x + 15 = 32
isolate the x's on one side, and all other numbers on the other.
so -3x = 9
Also 2 negatives gives a positive (-5 times -3) = positive.

3x - 24 + 8x = 53
same thing just isolate the sides so 11x = 77, and yea

looks like high school alegebra, or are you in college?

Here's all of the solutions, written out.

2 (x + 4) - 5 (x - 3) = 32
2x + 8 -5x +15 = 32
-3x +23 = 32
(-3x +23) - 23 = 32 - 23
-3x = 9
x = -3

3 x - 8 (3 - x) = 53
3x - 24 + 8x = 53
3x + 8x - 24 = 53
(11x - 24) + 24 = 53 + 24
11x = 77
x = 7

Use the associative and distributive properties to solve for x. :thumbsup:

Hope this helps you understand it better.

Thanks bob! Enjoy your new green rep box

and its algebra 2 in college. Im horrible in math. Im actually on the phone w/ my fiance as i type. hes got a degree in accounting and business law...hes helping me

Fuck math. Math can die. I hate, hate, hate, hate, hate, hate, hate, hate math. Its worthless. A complete waste of time and energy. Even while sober.

Reb, dont be so mean... if were not by the math, there would not be computers, and you wouldnt be posting here right now... to say the least...
Also, if you hate it, you wont understand it... i know very well how is to hate some subjects, and can say that it doesnt help... maybe if you find a good teacher that make you understand it well, maybe you will hate it less, and even like it.
Im a teacher myself, but im afraid im too far to be useful for you... anyway, good luck! :thumbsup:

lol I said the same thing for my entire school career, always slept through math class.

Until I got into college physics and the first few days were a review of the basic Calc and Trig that I did NOT know...

But that ended up not being a problem.. when the world is explained in terms of physics, and the mathematical equations that arise, you actually get to see a visual representation of math, and why and how it works. Then all those many confused little dots began to connect to each other. Take an introductory physics course if you have an elective you want to fill, it might help alot with your understanding of math, I know it did for me. Just make sure you ask around and find the best physics teacher, because thats 95% of it.

Yeah well im going for teaching and I can say that I will not ever use this.

Its not that its hard, its that its even harder to do because all my classes are online. So if I do need help or if i'm lost I have to call the teacher (God knows I better make it between the certain 3 hour period she allows calls or else she'll shit a brick).

I don't mind doing math i'll use. But i'll never use this. I still get A's in all my classes but man, taking 15 minutes to do a problem is freaking ridiculous.

Oddly enough there have been instances in my life when Ive needed to solve a real world problem with algebraic equations, and I was in a daze the whole time because I said the same things you did, and I was struggling to remember the right formulas. You say you will never use it, as I said the same thing, but we are both very young, and you are just beginning college life. I hate to tell you this, but you will use it alot more than you think you will, both in and out of school.

However... taking classes online fucking blows, and its made even worse when you dont enjoy or understand it. Best of luck hon, hope it gets better for you! If you need any help I got your back... along with many members of this site that are probably more qualified lol.
