In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable.
In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression.
In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
No, but eliminating variables is one of several ways to find the value of variables in a system of equations.
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
Finding a set of value for the set of variables so that, when these values are substituted for the corresponding variables, all the equations in the system are true statements.

1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.
When a given set of values for the variables are substituted in the expression the result is the value of the expression.
Calculating the value of the expression when you have substituted numerical values for the variables.
the value of variables is determined by the equation, discrete variables have absolute single value while the continuos have a range value
a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
No, but eliminating variables is one of several ways to find the value of variables in a system of equations.
A responding variable is a value of measure, that came from the manipulated and controlled variables.
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
Finding a set of value for the set of variables so that, when these values are substituted for the corresponding variables, all the equations in the system are true statements.
Independent variables are the input value of a function (usually x) and dependent variables are the output value of the function (usually y).
if two variables are positively related,it means that the two variables change in the same direction.that is,if the value of one of the variables increases,the value of the other variable too will increase.for example,if employment as an economic variable increases in a country,and price of goods too increases then we can say that these two variables(employment and price) are positively related
Explanatory (or independent) variables are variables such that changes in their value are thought to cause changes in the "dependent" variables.
Some languages assign a default value as 0 to uninitialized variables. In many languages, however, uninitialized variables hold unpredictable values.
