Question

What is the coefficient of $x$ in the expression$4x+3y$?

Answer 1

Determining the coefficient of $x$ in the expression$4x+3y$.

A coefficient is a number that is multiplied by a number. Consider, for example, the polynomial $a{x}^2+bx+c$.

In the above polynomial, $a$ is the $x^2$ coefficient, $b$is the $x$ coefficient, and $x$ is a variable.

A variable has no set value and can fluctuate, but a coefficient has not.

Hence, the coefficient of $x$ in the expression$4x+3y$ is$4$.
