What is the coefficient of x in the expression?

6x + 9y + 15z

6

Step-by-step explanation:

The constant near x is the coefficient of x

So, 6

Answer: 6

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.

In this case we want to find the coefficient that has x. 6 is the only coefficient in the expression 6x + 9y + 15z that has the coefficient of x.

Basically, a coefficient is simply a number that has a variable after it.
