Any number at all has the specified property.
==========
As correctly noted above, if you are performing exactlythe same operation (in this case adding or subtracting the same specific number) to both sides of an equation then it does not matter what number you use. Any number whatsoever may be used. This is because both sides will remain balanced.
Here is a concrete example:
Suppose 2x = 14
We could solve this as:
2x = 14
x = 14/2
x = 7
But we could also write the above equation as:
2x + 3 = 14 + 3
for:
2x + 3 = 14 + 3
2x + 3 = 17
2x = 17 -3
2x = 14 (we have reached the same position as above!)
x = 14/2
x = 7
You could substitute any number whatsoever and we will always end up with x = 7 here.

What is the equation for a number subtracted from -18 amounts to 156?
x - 18 = 156. The x is the unknown quantity, the rest of the equation you have. Now solve it and prove it.
What is meant by the word eigenvalue?
The term "eigenvalue" refers to a noun which means each set of values of parameter for which differential equation has a nonzero solution. It can also refers to any number such that given matrix subtracted by the same number and multiply to the identity matrix has a zero determinant.

2x - 12 = 8
How do you know when a number is not a solution of an equation?
When you put the number in place of the variable (like maybe the 'x' or the 'y') wherever the variable occurs in the equation, and the statement you get out of all the numbers you have is not true, then you know the number is not a solution.
What is the property that you can subtract the same number from both sides of an equation the new equation will have the same solution?
The property is: If equals are subtracted from equals, the results are equal.
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 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.
What is an equation for a number subtracted from five is ten?
x-5=10
What is a number in an equation that is not multiplied by a variable added or subtracted to a variable called?
a constant
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
Number that makes an equation true?
A number that makes an equation true is its solution.
If a number is subtracted from its square and the result is 2 what is the number?
The algebraic equation becomes x2 - x = 2 (or) x2 - x - 2 = 0 This has the solution (x-2)(x+1) = 0 so the answer is either 2 or -1.
When twelve is subtracted from twice some number the result is 6?
If you are looking for what number it is, it can be described by this equation: 2x-12=6. Solving this equation x=9.
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.
When 18 is subtracted from the square of a number, the result is 3 times the number. Find the positive solution?
The number you are referring to is 6.
When can you say that a number is called a solution in algebraic expression?
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.
