Let's define the unknown number as \( x \).

The phrase "twice a number" means \( 2x \).

Now, you are asked to subtract 14 from twice that number, which gives 4. This gives the equation:

\[
2x - 14 = 4
\]

### Solving for \( x \):

1. Add 14 to both sides to isolate the term involving \( x \):

\[
2x = 4 + 14
\]
\[
2x = 18
\]

2. Divide both sides by 2 to solve for \( x \):

\[
x = \frac{18}{2} = 9
\]

So, the number is \( x = 9 \).

Here are 5 related questions:
1. What happens if you subtract 14 from three times a number instead?
2. How would you solve \( 2x - 14 = 10 \) instead of 4?
3. What if the equation was \( 3x - 14 = 4 \)? How does the solution change?
4. How do you solve \( 2x + 14 = 4 \)?
5. Can you form a similar equation if the result was 6 instead of 4?

**Tip**: Always isolate the variable by using basic arithmetic operations step-by-step!
