An open number sentence is a sentence which contains a variable. A variable is a unknown number but replaced with a letter and can be on either side of an equals sign.
3x + 8 = 4x + 23x - 4x = 2 - 8-x = -6x = 6
You need to clarify the function AND provide an interval.
an open circle on a number line means the answer is just less than or greater than (< or >), but a closed circle means the answer is less than or equal to, or greater than or equal to (< or > with a line under it)
A value that satisfies an open sentence is called a solution or a root of the open sentence.
a solution
To determine if a given value is a solution to an open sentence in math, substitute the value into the equation or inequality. Then, simplify the expression to see if it holds true. If the resulting statement is valid (e.g., a true equation or a satisfied inequality), the value is a solution; if not, it is not a solution.
an open sentence can be either true or false, depending on what values are substituted for the variables. A SOLUTION of an open sentence with on variable is a value that makes the sentence true. The solution of the equation x+3=5 is 2. One solution of the inequality x-1>4 is 6, and there are many more solutions. hope this helps
An open number sentence is a sentence which contains a variable. A variable is a unknown number but replaced with a letter and can be on either side of an equals sign.
A replacement value for a variable in an open sentence is a specific number or expression that can be substituted for that variable to make the sentence true. For example, in the open sentence ( x + 3 = 7 ), the replacement value for ( x ) would be 4, as substituting 4 yields a true statement. Open sentences often represent equations or inequalities that depend on the value of the variable.

no it is a closed equation.
No, it is a FALSE statement.
3x + 8 = 4x + 23x - 4x = 2 - 8-x = -6x = 6
