Answer:
The coefficient of x is 3.
Explanation:
In the given expression, 4 + 3x + 5y, the term "3x" represents the product of the coefficient and the variable x.
A coefficient is a numerical factor that is multiplied by a variable. It indicates the amount or quantity associated with the variable. In this case, the coefficient of x is 3 because it is the number that is multiplied by the variable x.
So, in the expression 4 + 3x + 5y, the coefficient of x is 3.
