Four times the difference of 17 and a number is 84.

Which equation below can be used to find the unknown number?

So use n for the number

4 (17 - n)= 84

Hoped this helped (:

To find the unknown number in this problem, we can start by assigning a variable to represent the unknown number. Let's say the unknown number is represented by the variable 'x'.

The problem states that the difference of 17 and the unknown number is multiplied by 4 and the result is 84.

We can write this information as an equation. The difference of 17 and the unknown number can be written as (17 - x). Multiplying this difference by 4 gives us the equation:

4(17 - x) = 84

This equation can be used to find the value of the unknown number.
