How do I plug in a variable?
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
The value for a variable that results in a true sentence is called an?
a "solution"
What is to replace a variable with a number or anotherexpression in an expression?
The term for replacing a variable with another value or expression is "substitution."
What does it mean to evalutate the expression?
Replace each variable in the expression by its value and then find the value of the expression.
To evaluate a variable you must values for the variable and then calculate the result?
No. To evaluate a variable, you simply take its value. When you assign a value to a variable, the evaluation of that operation is the value of the variable after assignment. There is no calculation required to evaluate a variable, unless that calculation is part of the right-hand operand of an assignment operation, in which case the calculation is evaluated first and the result of that evaluation (the value) is then assigned to the variable which is then evaluated.
What is the result of substituting a value for a variable in a function?
To find the value of the other variable

To solve a system of equations you cannot replace a variable with an equal value or expression?
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
How do you substitute values in a formula?
It means that if you know the value of a variable, you replace every occurence of the variable with the value. For example, if x = 10, and you have the expression x2 + 5x - 3, you replace every x with 10, to get 102 + 5(10) - 3.It means that if you know the value of a variable, you replace every occurence of the variable with the value.
