What is the difference between a closed and open sentence?
A closed sentence is a mathematical sentence that is known to be either true or false. An open sentence in math means that it uses variables and is not known whether or not the mathematical sentence is true or false. When given the values of the variables, it is possible to plug them in to determine if the open sentence is true or false.

What is the solution of the open sentence?
The method of finding the values of variables that result in a true sentence is known as solving the open sentence. The replacement value is known as the solution of the open sentence. For example, 1 - y = 8 is an open sentence because the value of ‘y’ is unknown and as a result, we can state if it is true or false.

How to solve a sentence with addition and subtraction?
Step 1: We will use the addition and subtraction inverse operation to solve the given open sentence. Subtracting 4 from both the side, we get: y + 4 - 4 = 16 - 4 (1) Step 2: Simplify the equation (1) until you get variable = value. y + 4 - 4 = 16 - 4.
What is an inverse operation?
An open sentence can also be solved using inverse operations. The inverse operation does the opposite of another operation. Addition and Subtraction are inverse operations, whereas Multiplication and Division are inverse operations.
What is an open sentence in math?
An open sentence in Mathematics is neither true nor false until the variables have been substituted by specific values. The method of finding the values of variables that result in a true sentence is known as solving the open sentence. The replacement value is known as the solution of the open sentence.
