Want this question answered?
Solving for one variable makes it easy to put in a value for the other variables, and find a value for the first variable.
Not sure that you can slove anything. -2w = r + s is one linear equation in 3 unknown variables. You need three independent equations in 3 variables to be able to solve them.
I'll explain the "why" for now. The idea is that mathematicians want to be able to solve as many integration formulae as possible, in an exact way.
It is an equation because it is telling you that one thing (or a combination of things) equates to something else.There is not enough information to solve this equation however as there are an infinite number of solutions knowing only that 6x - 3y = 9.Here are just 2: x = 2 and y = 1 or x = 3 and y = 3.To solve this we need to know (or be able to calculate) the value of one of the variables first (either x or y) so that we can then calculate the other.For this type of question (where there are 2 unknowns) you will usually either be told the value of one of the variables which you can then substitute into the equation, or you will be given two equations which are true for the same values of each variable (known as simultaneous equations). As the value for the two variables is the same in each equation we are able to use this extra information to solve them.
well it is something that varies but is also able

If there are two variables, you'll usually need two equations in the two variables, to be able to find a specific solution. How you write the equation depends on the specific problem. In general, it requires some practice, to be able to convert a word problem into mathematical equations.
Without variables, you won't be able to do much programming. Variables is where you store data; such data may change over time. And computer programming is all about manipulating data.

In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks
Algebraic equations with two variables will need two equations to be able to solve it. Then, you can solve it with either substitution, adding/subtracting them together, or graphing! Those are the basic steps... For example: An instance of substitution: 2x + 1 = y + 2 x + y = 3 You could isolate y in the second equation to equal y = 3-x. Then in the first equation, substitute y with what it equals to 2x + 1 = 3-x+2 Then you can solve for x!

The freedom of assembly is important because people should have the right to get together. Groups often are able to solve problems that individuals cannot.

It is so that the experiment is a fair test. In order to protect the integrity and / or accuracy of the experiment and its results, you have to be able to control all the variables so that you know exactly why something is happening. If you do not control the variables, then one of them could be the reason for the results, and you won't be sure why you got the results you did.
