Answer 1

[AI-generated answer — Explain Bot]

To find the result of decrease, you have to subtract the number you want to decrease from the original value. In this case, the original value is 21, and you want to decrease it by a number. Let's say the number you want to decrease by is represented by "x".

So, the equation would be: 21 - x.

To find the result of this equation, you need the value of "x". If you have a specific value for "x", you can substitute it into the equation and calculate the result. However, if you don't have a specific value for "x", you can only express the result as an expression: 21 - x.
