insert the answer in the equation, replacing the variable, and see if it still makes sense.

What do you call the solution of a equation derived from an original equation that is not a solution of the original equation?

That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.


What equation is a integer?

An integer is not an equation, but rather a counting number.


How do you guess and check to find the solution set of the equation x-54?

You cannot. x - 54 is an expression not an equation. An expression has no solution set since there is nothing to solve.


Is anything named after Pierre de Fermat?

Yes, the famous Fermat's Last Theorem, a conjecture by Fermat, that an equation of the form an + bn = cn has no integer solution, for n > 2. This was conjectured by Fermat in 1637, but it was only proved in 1995.Yes, the famous Fermat's Last Theorem, a conjecture by Fermat, that an equation of the form an + bn = cn has no integer solution, for n > 2.

What is the smallest integer solution of 17?

17 is not an equation and so there can be no "solution of 17". There is, therefore, no possible answer to the question.


How do you check the solution to an equation?

plug your solution back into the original equation and work it out again

How do you check a solution to an equation?

By substitution.


What is the word for a number that makes an equation true?

Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.

Why is it possible to check the solution to any equation?

If you found the value of x that is a solution to an equation, you want to substitute that value back into the original equation, to check that it indeed satisfies the equation. If it does not satisfy the equation, then you made an error in your calculations, and you need to rework the problem.

How do you check to see if the value of the variable is a solution to the equation?

Substitute that value in the equation, and then check to see if the resulting statement is TRUE.


Why is 24 not a factor of 12?

That simply means that there is no integer solution to:24n = 12 For comparison, 4 IS a factor; so the equation: 4n = 12 DOES have an integer solution.
