The equation is \(2*(c-4) = 7\).
Explicación
## Step 1The problem is asking us to translate the sentence "Twice the difference of a number and 4 is equal to 7" into an equation. The variable we are using is 'c'.## Step 2The phrase "Twice the difference of a number and 4" can be translated into the mathematical expression \(2*(c-4)\). Here, 'c' represents the unknown number, and '4' is the number we are subtracting from 'c'. The result of this subtraction is then multiplied by 2.## Step 3The phrase "is equal to 7" translates to '= 7' in mathematical terms.## Step 4Combining the expressions from Step 2 and Step 3, we get the equation \(2*(c-4) = 7\).
