I need help please:

Express in symbols:"Six decreased by the product of a number and six is twenty."

product of a number and six: 6x

6 decreased by n is 6-n, so you wind up with

6 - 6x = 20

Your equation looks good! :D

To express the given statement using symbols, we need to identify the unknown number. Let's call the unknown number "x".

The statement "Six decreased by the product of a number and six is twenty" can be written in symbols as:

6 - (x * 6) = 20

In this expression, "6" represents the initial number, "x" represents the unknown number, and "(x * 6)" represents the product of the unknown number and six. The expression states that when we decrease six by the product of the unknown number and six, the result is twenty.
