0what is the number that can replace a variable in a equation to make it a true equation? 8 letters this is not a good answer go look 4 a notha one

It's called the "solution" of the equation.

The number that replaces a variable is the solution to the equation. great question, but it's only the answer.??

It is to make the variable the subject of the 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.

Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number

The goal is to find what value or values the variable may have, to make the equation true.

They are called the "solutions" of the equation.

When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying

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.

It is finding the values of the variable that make the quadratic equation true.

That means the same as solutions of other types of equations: a number that, when you replace the variable by that number, will make the equation true.Note that many trigonometric equations have infinitely many solutions. This is a result of the trigonometric functions being periodic.

The graph of an equation is all of the answers that are true for the equation. A variable is an unknown number in an equation. Most equations are written with x and y variables. There are an unlimited amount of numbers that the variables can be to have the equation be true, so you would graph the equation to show the unlimited amount of numbers that make the equation true.

you can make something equal something else to find a variable.

it is basically an equation without an equals sign. usually has a variable in it.

It is about finding a value of the variable (or variables) that make the equation a true statement.

1. Elimination: Select two equations and a variable to eliminate. Multiply each equation by the coefficient if that variable in the other equation. If the signs of the coefficient for that variable in the resulting equations are the same then subtract one new equation from the other. If they have opposite signs then add them. You will now have an equation without that variable. Repeat will other pairs and you will end up with one fewer equation and one fewer variable. Repeat this process: after each round you will have one fewer equation and one fewer variable. Keep going until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.2. Substitution: Select a equation and a variable. Make that variable the subject of the equation. The right hand side of this equation is an expression for that variable. Substitute this expression for the variable is each of the other equations. Again, one fewer equation in one fewer variable. Continue until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.3. Matrix inversion: If A is the nxn matrix of coefficients, X is the nx1 [column] matrix of variables and B is the nx1 matrix of the equation constants, then X = A^-1*B where A^-1 is the inverse of matrix A.

You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.

The solution of an equation means the number that the variable must bein order to make the equation a true statement. If the variable has anyother value, then the equation is not true.For example, here's an equation:x - 4 = 2Can 'x' be 5 ? If it is, then 5-4=2. That's not true, so 'x' can't be 5.Can 'x' be 9 ? If it is, then 9-4=2. That's not true, so 'x' can't be 9.Can 'x' be 6 ? If it is, then 6-4=2. That's true. So '6' is the solution to the equation.

numbers are equation because there are numbers in equation which make numbers equation
