What is a number that can replace a variable in an equation to make it true called?
It's called the "solution" of the equation.
What is the number that can replace a variable in an equation to make it a true equation?
what 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
What is an equation with one or two variables?
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
How do you determine the values of x and y in a linear equation in two variables?
There are 4 ways to do it. You can graph, use substitution, use elimination, or use matrices. Graphing: Graph the two equations and the coordinates where they intersect are the answer. Substitution: Solve one of the equations for one of the variables and substitute that in the other equation. Then you'll find the value of that variable and you can substitute that and get the other variable. Elimination: Make the coefficients of one of the variables opposites of each other and then add both equations. The opposites will cancel and you have the other variable. Then when you find that variable, find the other one by substituting the number for that variable in one of the equations. Matrices: Make sure both equations are in standard form (Ax+By=C). Then make a 2x2 matrix that has the coefficients of x in the left column and the coefficients of y in the right column and each equation gets its own row. Then make a 2x1 matrix with the C values. Put the C value of the equation you put at the top at the top and the other one at the bottom. Then multiply the inverse of the 2x2 matrix by the 2x1 matrix and you'll get a 2x1 matrix with x at the top and y at the bottom.
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.
Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
What do you call the number that replaces a variable to make an equation?
The number that replaces a variable is the solution to the equation. great question, but it's only the answer.??

Can you solve a variable with an 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.
What is it called when you have to get the variable alone on one side of an equation?
It is to make the variable the subject of the equation.
What is the goal of solving an equation with one variable?
The goal is to find what value or values the variable may have, to make the equation true.
What are the values of the variable that make an equation true called?
They are called the "solutions" of the equation.
How do you use different techniques to solve linear equations?
There are several techniques to solve linear equations. One common technique is the elimination method, where you eliminate one variable by adding or subtracting equations. Another technique is substitution, where you solve one equation for a variable and substitute it into the other equation. You can also use matrices and row operations to solve linear equations.
What is the solving for the roots of quadratic equation?
It is finding the values of the variable that make the quadratic equation true.
