The equation \( |y| = -18 \) has no solution. 

This is because the absolute value of any real number is always non-negative (i.e., \( |y| \geq 0 \)). Therefore, it is impossible for the absolute value of \( y \) to equal a negative number like \(-18\).

Would you like more details, or do you have any questions?

Here are 5 related questions for further practice:
1. Solve \( |x| = 5 \).
2. What is the solution to \( |y| = 0 \)?
3. Can \( |z| \) equal \(-7\)? Why or why not?
4. Solve the equation \( |3x| = 9 \).
5. What is the solution to \( |2y - 1| = -3 \)?

**Tip:** Always check if the absolute value equation is set equal to a non-negative number before attempting to solve it.
