Given that \( x = -15 \), there isn’t much further information provided, but if you’re looking to solve or explore anything with this equation, here are a few possibilities:

1. **Basic substitution**: If this value of \( x \) is part of a larger equation, you can substitute \( -15 \) in for \( x \) to simplify or solve that equation.
   
   For example, in an expression like \( 2x + 5 \):
   \[
   2(-15) + 5 = -30 + 5 = -25
   \]

2. **Plotting**: On a number line, \( x = -15 \) would be placed 15 units to the left of zero.

Would you like to see further examples of this value used in different contexts, like solving an equation or plotting? Here are some related questions:

1. What would happen if you squared \( x = -15 \)?
2. How does \( x = -15 \) affect the solution of the equation \( 2x + 7 = 0 \)?
3. Can you simplify or solve an equation involving \( x^2 \) with \( x = -15 \)?
4. What is the absolute value of \( x = -15 \)?
5. How does \( x = -15 \) affect the graph of a linear equation like \( y = 2x + 5 \)?

**Tip**: The absolute value of any negative number is its positive counterpart, e.g., \( |x| = |-15| = 15 \).

Explore the substitution of x = -15 into basic arithmetic expressions and equations, such as y = 2x + 5, and how to solve them. Learn about the concept of absolute value and how to represent x = -15 on a number line. Suitable for students in Grades 6-8.
