Translate the sentence into an equation. Twice the difference of a number and 9 is equal to 2. Use the variable x for the unknown number. square

## Step 1<br />The problem asks us to translate the sentence "Twice the difference of a number and 9 is equal to 2" into an equation. The variable \(x\) is used to represent the unknown number.<br /><br />## Step 2<br />The phrase "Twice the difference of a number and 9" can be translated into mathematical terms as \(2*(x-9)\). Here, \(x\) represents the unknown number, and \(x-9\) represents the difference between the number and 9. The entire expression is then doubled, which is why we use \(2*(x-9)\).<br /><br />## Step 3<br />The phrase "is equal to 2" translates to \(= 2\) in mathematical terms.<br /><br />## Step 4<br />Combining the expressions from Step 2 and Step 3, we get the equation \(2*(x-9) = 2\).
