Identify the expression for the following:

A number subtracted from -20.


Sagot :

To identify the expression for the scenario where a number is subtracted from -20, let's break it down step by step.

1. Let the variable [tex]\( x \)[/tex] represent the unknown number.

2. According to the problem statement, we need to subtract [tex]\( x \)[/tex] from -20.

3. The operation described, "subtracted from," means that we start with -20 and then remove [tex]\( x \)[/tex] from it.

4. Therefore, the expression takes the form:

[tex]\[ -20 - x \][/tex]

Thus, the expression for a number subtracted from -20 is [tex]\( -20 - x \)[/tex].
