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.
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".

You cannot solve one linear equation in two unknown variables.
To solve for 2 unknown variables you need 2 independent equations. You have only 1.
To understand the formulas and concepts in algebra very easily and also in order to solve the problem much efficiently
It might help if you specified why WHAT was important in random variables.
There is no limit to the number of variables a formula can have.
The answer depends on the variables plotted in the graph.
There is no limit to the number of variables a formula can have.
Yes, that is what you are normally required to solve for.
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
you cannot solve this without more information. When 3 variables are involved, you need 2 equations to solve for the answers for both variables.
Usually you would use one of the formulae for constant acceleration, replace the variables you know, and solve for the variables you don't know.
It can represent formulas like A=L×W etc...
