Explanatory (or independent) variables are variables such that changes in their value are thought to cause changes in the "dependent" variables.
You isolate variables in math because the point of an equation is to solve for the variables. By isolating the variables you have learned what that variable stands for and thus solved the equation.
There can be. It depends on the variables.
3 variables

The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
You can swap two variables, by storing one of them temporarily in a third variable, like this: temp = a; a = b; b = temp; Inside a function, this won't work, because the function parameters are COPIES of the original variables, not the variables themselves. Any change won't affect the original variables. If you work with OBJECTS, and swap the CONTENTS of the objects (not the object pointers), it can work, though.
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.
Its arbitrary - that's how the word (work) is defined.
We need an equation to work with.
yes. 2 variables can be written in one statement. take for example the equation y=3x+5, as long as you have a single solution to work with there can be 2 variables.
To find the correct variables or answer from a series of problems labs.
go to google and type in cp variables and go to the first one on the first page they really work :D
Various programs will not work causing you to have to reinstall them
Variables, Literals, and Named constants.
Test variables are the factors that are intentionally changed or manipulated by the researcher in an experiment, whereas outcome variables are the factors that are measured and affected by the test variables. Test variables are the independent variables that are controlled by the researcher, while outcome variables are the dependent variables that change in response to the test variables. The relationship between the test variables and outcome variables is explored to determine the effect of the test variables on the outcome variables.
