In `-7xy^(2)z^(3)`. write down the coefficient of:
`x`

Answer

To find the coefficient of \( x \) in the expression \(-7xy^2z^3\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Expression**: We start with the expression given, which is \(-7xy^2z^3\).

2. **Understand Coefficients**: A coefficient is a numerical factor in a term of an algebraic expression. In this case, we are looking for the coefficient of the variable \( x \).

3. **Extract the Coefficient**: In the expression \(-7xy^2z^3\), the coefficient of \( x \) is the numerical factor that multiplies \( x \). Here, the numerical factor is \(-7\).

4. **Write the Coefficient**: Therefore, the coefficient of \( x \) in the expression \(-7xy^2z^3\) is \(-7\).

### Final Answer:
The coefficient of \( x \) in \(-7xy^2z^3\) is \(-7\).
