1(: if the variable is not given to you
Two expressions to show a number decreased by 11 are ( x - 11 ) and ( 11 - x ). The first expression, ( x - 11 ), directly represents the number ( x ) reduced by 11. The second expression, ( 11 - x ), indicates the difference when ( x ) is subtracted from 11, but it represents a different value depending on the value of ( x ).
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
There is an infinite number of such expressions eg x = 1 + 1; x = sqrt 4 etc etc. I've a feeling you need to be more precise with your wording!
When a number is multiplied by a variable, it creates a term that represents the product of the two. For example, in the expression (3x), the number 3 is multiplied by the variable (x). This means that the value of (3x) will change depending on the value of (x). Such expressions are commonly used in algebra to represent relationships and solve equations.

It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.

There are many expressions that have this value. The simplest one is the number zero itself.

To find the excluded value for the expressions ( x + 3 ) and ( 2x - 4 ), we need to identify values of ( x ) that would make the expressions undefined, such as division by zero. However, since neither ( x + 3 ) nor ( 2x - 4 ) involves any division, there are no excluded values for ( x ). Thus, both expressions are defined for all real numbers.
