A number that stands by itself is called an?
It may be called "the constant term".
Tariq said you can write an equation by setting an expression equal to itselfWould an equation like this be trueexplain?
Yes. Any number, or expression, is equal to itself. An equation such as:x + 5 = x + 5 is true for ANY value of "x".
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.
When a number is decreased by 20 of itself the result is 32. What is the number?
Let's represent the number as x. The equation for the given scenario can be written as x - 20x = 32. Simplifying this equation, we get -19x = 32. Dividing both sides by -19, we find that x = -32/19, which is approximately -1.6842. Therefore, the number is approximately -1.6842.
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.
