Plug your answer back into the original equation.
Example:
3x+15=21
x=2
3(2)+15=21

How to check the solution to an integer equation?
insert the answer in the equation, replacing the variable, and see if it still makes sense.
What does it mean when it says determine whether the given value of the variable is a solution?
I'm going to assume you have an equation to go with your variable? It means "Check if this number works" What to do is put the given value into the equation instead of the variable and see if the result is true - if it is you have a solution, if not you don't. I'll make one up as a demo: Equation : a + 4 = 7 is a = 2 a solution? a+4=7 2+4=7 6=7 (FALSE!) No this given value is not a solution.
How can you check to see if a number is part of the solution set of an inequality?
You replace the variable by the number, do all specified calculations, and then check whether the resulting inequality is true or false. This is basically not very different from checking a solution of an equation.
How can one tell when a math problem has no solution?
Depends on the type of math problem. there's usually an equation to see if there is a solution or not.
How do you check the quadratic formula?
Substitute your answer in the original equation and see if it works out.
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.

What is the solution to the equation y equals -2.5?
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
What are the steps to solving a radical equation?
Details may vary depending on the equation. Quite often, you have to square both sides of the equation, to get rid of the radical sign. It may be necessary to rearrange the equation before doing this, after doing this, or both. Squaring both sides of the equation may introduce "extraneous" roots (solutions), that is, solutions that are not part of the original equation, so you have to check each solution of the second equation, to see whether it is also a solution of the first equation.
What is the solution in a scientific process called?
One of the last steps is called the conclusion. You would then repeat the process many times to check to see if you are correct.
How do you determine whether a number is a solution of an equation?
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.

What is the solution to the equation 0.5x 3.5 6?
Write the operations out in words. You can see that they do not appear in the question.
How do you check your answer to an equation?
When you are solving an equation usually you are solving for x. If you want to check your answer just plug the values you got back in to the original function. Or you can use a different method to solve the equation and see if you get the same answer.
