You replace the variable by the purported solution, and do all the calculations. If you end up with a true statement, for example 5 = 5, then it is a solution.
Substitute the number in place of the variable. Evaluate the expressions. If the resulting equation is true then the number is a solution.

What is the discriminant and how is it used to solve equations using the quadratic formula?
It is not to solve so much as to see the number of solutions and whether there is a real solution to the equation. b2 - 4(a)(c) A positive answer = two real solutions. A negative answer = no real solution ( complex solution i ) If zero as the answer there is one real solution.
Which equation has a solution of -4?
There are an infinite number of equations with this solution, eg x = 6 - 10; x = 45678 - 45682; x squared = 16 etc etc
How do you solve this graphing equation y plus x equals 6?
The solution consists of the infinite number of points on the line which is defined by y + x = 6.
How do you solve for x if the problem is 3x plus 20?
You haven't given the solution to the equation ! 3x + 20 = ? If you have the number for the question-mark - you can find the value of x ! For example in the equation 3x + 20 = 50... the value of x is 10.
What is the solution for 9.4605284 x 1012?
There can be no solution to a number. That is like asking what is the solution to 3!
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
How do you determine if a number is a solution of an equation?
plug your answer it to the original question
How do you determine whether the equation is balanced?
To determine if an equation is balanced, compare the number of each type of atom on the reactant side to the product side. Make sure there is an equal number of each type of atom on both sides of the equation. If the number of atoms is balanced, the equation is balanced.
What is A number that makes a equation true?
The solution set is the answers that make an equation true. So I would call it the solution.
Using the Kw equation how is it possible to determine whether an aqueous solution is acidic basic or neutral?
By calculating the concentration of hydronium ions and hydroxide ions in the solution and comparing them to the equilibrium constant for water (Kw = 1.0 x 10^-14 at 25°C), you can determine the pH value of the solution. If [H3O+] > [OH-], the solution is acidic; if [OH-] > [H3O+], the solution is basic; and if [H3O+] = [OH-], the solution is neutral.
How many solutions does the equation have?
The number of solutions an equation has depends on the nature of the equation. A linear equation typically has one solution, a quadratic equation can have two solutions, and a cubic equation can have three solutions. However, equations can also have no solution or an infinite number of solutions depending on the specific values and relationships within the equation. It is important to analyze the equation and its characteristics to determine the number of solutions accurately.
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.
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
Math tell whether the ordered pair is a solution of the equation?
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
Number that makes an equation true?
A number that makes an equation true is its solution.
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.
What is the number that can replace a variable in an equation to make it a true equation?
The number that can replace a variable in an equation to make it a true equation is called the solution or root of the equation. This number satisfies the equation when substituted for the variable. In algebra, finding the solution involves solving for the variable by performing various operations to isolate it on one side of the equation. The solution is the value that balances both sides of the equation, making it true.
