You cannot write the quotient itself as an equation, but you can express a division operation and use an equation to express that the result of this operation (the quotient) is a specific value. For example, 16/8 =2.

find the variable(s). then write the equation(s). finally simplify the equation(s)

You write an equation that involves an independent variable (for example "x"), a dependent variable (for example "y"), and the first derivative, or higher-level derivatives, of the dependent variable (for example, dy/dx).

Read the problem. Write each fact as a variable expression. Write each fact as a sentence.

You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

1.) write down question 2.) cry. 1) Read the question through until you understand it 2) Find out what it asking you to solve for 3) Write down what is given like equations, variables, constant like pi. ...etc 4) Write down what your solving for. 5) Setup your solution to the problem by doing the following : A) Write : " Given:" B) what equation you are using to solve it C) any constant like pi, e, 10^...etc D) what you are solving for. E) Write: "Step 1:" 5) Write down your equation, you are using to solve it. 6) Do you have to rearrange the equation to get what you are solving for? If so than do it. Show it in step 1 and use it instead of other Write out what math operation you are using to solve it in each of the step by step operation When you finally get your answer for it, do a proof or check for it. Write : " Proof or check" Write down the original equation Replace the found variable with the answer you got for Do the step by step operation and writing down what math operation you are using. If it equals than write : "It checks and equals ". If not - Backtrack to find your error, correct it, redo the proof again until it equals Move on to the next problem.

If you mean "spell" as meaning "to name or write letters of any word," then it's Subtraction.

x2 - 4x + 4 or (x - 2)2

Write the following as an algebraic expression using x as the variable: The sum of a number and -8

Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2

1) Solve the equation for the desired variable. 2) Write it in function notation. For example, if y = 2x + 3, it is already solved for "y"; just rewrite it as f(x) = 2x + 3.

A linear equation in two variables will give an infinite number of solutions. These will comprise the coordinates of points along a straight line in 2-dimensional space.

Yes, you can write an equation out in words. This is often done to make clear what the equation in numerals is.

The difference between eleven and five is six. When using difference in a mathematical equation it means subtraction. So it really means 11-5=6.

An example could be: 3x-2 = x-6 and so the variable x = -2

The dependent variable, y, is equal to 7 less than twice the independent variable, x.

Here is a example. "I wrote variable in a sentence."

An equation to find the value of the variable 104, 137, 154 and x with a mean of 130 is: (104 + 137 + 154 + x)/4 = 130 395 + x = 130 * 4 x = 145.
