Vlad spent 20 minutes on his history homework and then completely solved \( x \) math problems that each took 2 minutes to complete. What is the equation that can be used to find the value of \( y \), the total time that Vlad spent on his homework, and what are the constraints on the values of \( x \) and \( y \) ? \( y=2 x+20 ; x \) is any integer greater than or equal to 0 , and \( y \) is an integer greater than or equal to 20 . \( y=2 x+20 ; x \) is any real number greater than or equal to 0 , and \( y \) is any real number greater than or equal to 20. \( y=20 x+2 ; x \) is any integer greater than or equal to 0 , and \( y \) is an integer greater than or equal to 20. \( y=20 x+2 ; x \) is any real number greater than or equal to 0 , and \( y \) is any real number greater than or equal to 20.
