To Fill: The statement “Any replacement for the variable that makes an equation true is called a(n) _______ of the equation” with appropriate word by using given choices.
Answer to Problem 1VR
Solution:
Any replacement for the variable that makes an equation true is called a solution of the equation.
Explanation of Solution
Given Information:
The choices are addition principle, multiplication principle, solution, equivalent, equation and inequality.
Explanation:
The solution of the equation is the value of the variable which makes an equation true.
That is, the solution of the equation is any substitution for the variable that makes an equation true.
For example, consider an equation,
In the equation if the variable x is replaced by 5,
As, the value 5 is the replacement of variable x which makes equation true.
So, 5 is the solution of the equation.
Therefore, any replacement for the variable that makes an equation true is called a solution of the equation.
