1. You have that a student's pay of $18 an hour is $4 more than twice the amount the student earns per hour at an internship.
2. So, let's call the hourly pay of the internship: "x". Then, you have:
18=2x+4
3. When you clear the variable "x", you obtain:
18-4=2x
14=2x
x=14/2
x=$7
Therefore, the answer is: The hourly pay of the internship is $7.
