Algebra is the basis of maths you can use it to solve unknown terms such as x. For example: 3x - 3 = 0 3x = 3 x = 1

That depends entirely on the equation which has not been given but in general whatever is done on one side of an equation must be repeated on the other side in order to keep the equation in 'balance'

An equation is a statement. If it includes a variable, then it's only true for certain values of the variable and false for all others, and to "solve" it means to find those values. An equation without variables is also a statement. Either the statement is true or else it isn't. If the statement isn't true, then it's not an equation. Either way, it was nice of someone to hand it to you, but there's nothing that needs to be done with it. It asks no question, poses no problem, and seeks no solution.

Nothing specifically is "done" to the variable; variables are generally used to represent either:* A quantity that is initially unknown (and should be solved for), or * A quantity that can be anything - to analyze what happens no matter what a certain value is.

The unknown quantity that can be calculated after performing a titration is the concentration of the substance being titrated. This is typically done by using the volume of titrant required to reach an endpoint and applying stoichiometry to determine the concentration of the unknown substance.

In physics, the variable "w" can represent different physical quantities depending on the context. It is commonly used to represent work done, rotational frequency, weight, or other variables such as width or width of a wave. The specific meaning of "w" should be determined based on the equation it appears in.

No. They both represent manipulations of the same quantity of energy, but the first type inevitably causes a higher rate of perspiration.

A force can be represented as a vector quantity, with magnitude and direction. This is typically done using a diagram that includes a labeled arrow pointing in the direction of the force with a specific length to represent the magnitude.

I don't really know but usually it is done with one variable. If it has two variables there might be two unknown anwers to the equation.

In every formula, there are numbers and unknown values. What has to be done is to perform the calculation by removing the known value and leaving the unknown. For instance; x+3=5. In this case, one has two values that must be removed to discover the unknown value. So one has to perform the inversion of the formula to solve for the unknown quantity. Therefore, we "flip" the equation. Since X is the unknown, we must use what we have. Therefore we subtract (doing the inverse of the stated equation) 3 from the total of 5. The sum of the answer will give the unknown quantity, in this case 2. To prove that you are right, you "plug in" the value that you have solved for into the missing value space and perform the equation to see if the answer is correct.
