Answer:
3
Explanation:
We are given that Jill simplified an expression

We have to find the coefficient of x-term of the fully simplified expression
In order to find the coefficient of x- term we will rearrange the terms
Rearrange the terms and we get



Coefficient of x -term =Constant value multiply with x
Constant value multiplied with x term =3
Hence, the coefficient of x-term =3
