19-x

Step-by-step explanation:

Here,

total students=19

There are two types of students in the group.

Members and nonmembers.

Now, if x represents the number of students that are members.

then we can find the number of nonmembers by simply subtracting number of member from total students.

So, the number of nonmembers will be 19-x

Hence, expression for number of nonmember students in terms of x are (19-x)
