Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

3X + 8 = 12
Subtract 8 from both sides:
3X + 8 - 8 = 12 - 8
Reduce:
3X = 4
Divide both sides by 3
3X/3 = 4/3
Reduce:
X = 4/3
Or _
X = 1.33
Subtract 7x from each side: x - 2 = -9
Add 2 to each side: x = -7. Each side equals -58, job done.
What is two method of writing set?
You can specify a set either by listing all of its members (not an option for sets that are very large or even infinite), or by specifying some rule for elements to be a part of the set.
How do you solve 20log10X equals 5?
20*log10x = 5
Dividing both sides by 20: log10x = 5/20 = 0.25
Raising 10 to the powers: x = 100.25 = 1.7783 (approx)
How do you solve 5p plus 18 equals 8p?
5p+18 = 8p
Subtract 5p from both sides:
18 = 3p
Divide both sides by 3:
6 = p or as p = 6
What is the answer to y 20 - x equals?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2.
2x3 plus 7x2 - 16x - 5 is divided by x plus 5?
how should I know? I'm not a math genius!

Please only answer the question. If you don't know the answer please don't take up the space.
Simplify the top and you get 15-16X. The bottom is all ready as simple as it gets.
In this type of problem we have 15/5=3 and16X-X--5x. So the answer is 3-5X and X may not equal -5.

Sorry, sorry dude, just not that good at math. . . my answer was 4. wow i feel stupid. . .

My point is that we are trying to build a huge database for anyone to find the answers they need. Answers like "I'm not a genius" don't really contain any kind of answer. Just a heads up, not a big deal.
If the question is simplify (2x3 + 7x2 - 16x-5)/(x + 5), then (x + 5)(2x2 - 3x - 1)/(x + 5) = 2x2 - 3x - 1

My bad, I read it as 6+8-5-16x. Since the author didn't show any exponents. Thankyou for the correction.
What is 2x plus 8 equals 10 solve for x?
2x+8=10... Subtract 8 on both sides, then devide by 2... 2x=2... x=1
What is the solution to the equation -2x plus 3y equals 8?
The "solution" means the numerical values of 'x' and 'y' that make the statement true.
Right now, there are an infinite number of solutions. Here are a few of them:
X . . . . Y
-1 . . . . 2
2 . . . . . 4
5 . . . . . 6
8 . . . . . 8
11 . . . . 10
In general, you need the same number of separate equations as the number of "variables"
or "unknowns" in them.
Since your equation has two unknowns ... 'x' and 'y' ... you need another equation, in order to
pin the solution down to a single pair of numbers for them.
since x is negative you use the identity cot-1(x)=tan-1(1/x)+pi. Tan-1(1/-sqrt3) + pi 5pi/6 + pi =pi
