solution
What is a quantity that can have different values?
A variable.
What is x values?
They comprise a set of values for some variable x.
What is the solution of an equation?
the set of all values which, when substituted for unknowns, make an equation true. this is wrong
What is the best definition of a variable?
Symbols used to represent unspecified numbers or values.
What are the values of the variable that make an equation true called?
They are called the "solutions" of the equation.
What does solve the equation mean?
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.
Can you solve a variable with an equation?
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
How did you know that the values of variable raelly satisfy the equation?
You substitute the value of the variable into the equation and simplify. If the rsult is a true statement then that value of the variable really does satisfy the equation.
What are the values of a variable that make an equation true?
It is the solution; sometimes also called the root.
What is the goal of solving an equation with one variable?
The goal is to find what value or values the variable may have, to make the equation true.
What is the meaning of solution of an equation?
The solution to an equation consists of the value (or values) of all the variables such that the equation is true when the variable(s) take those values.
What is the solving for the roots of quadratic equation?
It is finding the values of the variable that make the quadratic equation true.
What does SOLVE stand for in math?
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
What is a special type of literal equation?
An identity is a special type of literal equation. It is true for all values of the variable.
Is a plus 2a equals 3a equation or expression?
It is, in fact, an identity - which is an equation which is true for all values of the variable.
Why would you want to solve a literal equation for a variable when you could simply plug in known values and then solve the resulting linear equation?
if you solve by plugging in the known values ahead of time you won't have a general formula for the variable in the literal equation. Therefor if the known values change, you would have to start all over again, making each problem more individualized. Once the literal equation is solved for some variable, if the known values change all you have to do is plug in those new numbers to your literal equation, and out pops your answer
