To translate the phrase ‘5 minus twice a number’ into an algebraic expression, we start by identifying the components of the phrase.
Firstly, the term ‘a number’ can be represented by a variable, typically we use ‘x’. This allows us to express any unknown value in our equation.
Next, the phrase ‘twice a number’ means we need to multiply our variable (x) by 2, which gives us ‘2x’.
Finally, the term ‘5 minus’ indicates that we need to subtract our previously defined expression (2x) from 5. Therefore, we can combine these elements to form the expression:
5 – 2x
This algebraic expression now accurately represents the original phrase, clearly indicating that we take 5 and subtract double the value of the variable (x).
