Write an equation that can be used to solve. Five decreased by twice a nimber

Answer 1

Let's denote the unknown number as \( x \).

The phrase "twice a number" means \( 2x \).

The phrase "five decreased by twice a number" translates to the expression:

\[ 5 - 2x \]

If you want to set up an equation based on this expression, you'll need an additional piece of information, such as what this expression equals. For example, if we want to set it equal to 0, the equation would be:

\[ 5 - 2x = 0 \]

Let me know if you have a specific value that this expression should equal!
