In the expression given, we need to identify the coefficient of the variable x. From the expression 6 4x 8 2 6 2 4 8, we can focus on the part that contains the variable x.
The term 4x represents the coefficient in this expression. Here, the number 4 is the coefficient of the variable x. Therefore, the coefficient is 4.
To summarize:
- Coefficient of a variable is the numerical factor that multiplies the variable.
- In the term 4x, 4 is the coefficient.
So, the answer is 4.
