Using the original form of the equation to check your solution ensures that you verify the accuracy of your answer within the context of the problem. It helps confirm that the solution satisfies all conditions and constraints set by the equation. Additionally, checking against the original form can reveal any potential errors made during the solving process, ensuring the integrity of your solution. This practice reinforces understanding and builds confidence in your problem-solving skills.
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.
Checking your solution in the original equation is always a good idea,simply to determine whether or not you made a mistake.If your solution doesn't make the original equation true, then it's wrong.
The property of equality that allows you to check a solution of an equation is the substitution property. This property states that if two values are equal, one can be replaced by the other in any expression or equation. By substituting the proposed solution back into the original equation, you can verify if both sides yield the same result, confirming whether the solution is valid.
Plug your answer back into the original equation.Example:3x+15=21x=23(2)+15=21
Put the values that you find (as the solution) back into one (or more) of the original equations and evaluate them. If they remain true then the solution checks out. If one equation does not contain all the variables involved in the system, you may have to repeat with another of the original equations.

If you mean for a math problem, after coming up with a solution you should usually check the solution in the original equation, to be safe.
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.

An "extraneous solution" is not a characteristic of an equation, but has to do with the methods used to solve it. Typically, if you square both sides of the equation, and solve the resulting equation, you might get additional solutions that are not part of the original equation. Just do this, and check each of the solutions, whether it satisfies the original equation. If one of them doesn't, it is an "extraneous" solution introduced by the squaring.

how can the reflexive property be applied to check the accuracy of a solution to equation?
By substitution.
Plug your answer back into the original equation.Example:3x+15=21x=23(2)+15=21
Put the values that you find (as the solution) back into one (or more) of the original equations and evaluate them. If they remain true then the solution checks out. If one equation does not contain all the variables involved in the system, you may have to repeat with another of the original equations.
It really depends on the type of equation, but in the simpler cases - those that you are likely to encounter in high school algebra - you will usually need to replace the purported solution into the original equation, then simplify the equation as appropriate. If this results in a true statement (for example, "5 = 5"), then the solution is correct; if you get a false statement (for example, "1 = 0"), then the purported solution is not correct.
