Firstly, you can combine like terms, or terms that have the same variable and exponents.
24x and 4x both have the variable "x" so it can be combined to make 28x
A coefficient is basically just the number that's used to multiply the variable
In this case, the variable is "x" and the number that will be multiplied to x is 28.
<em>The coefficient is 28.</em>
