write a one step equation not using zero where the answer is 4.

Explanation:

Step1: Choose an operation

We can use addition. Let the variable be (x) and we add a non - zero number to it to get 4. For example, if we start with (x) and add 2 to it and set it equal to 6. (x + 2=6) We can also use multiplication. Let (x) be the variable, and if we multiply (x) by 2 and set it equal to 8. (2x = 8)

Step2: Verify the solution

For (x + 2=6), subtracting 2 from both sides gives (x=6 - 2=4). For (2x = 8), dividing both sides by 2 gives (x=\frac{8}{2}=4).

Answer:

(x + 2=6) (or (2x = 8), there are multiple possible answers such as (x-3 = 1), (5x=20) etc.)
