Could be either of two things:
(Five) plus (six divided by the product of two times x):
5 + (6/2x) = 5 + (3/x)
or ir could be (Five plus six) divided by (the product of two times x)
(5+6)/2x = 11/2x
Since there are no parentheses in the statement to make it clear, PEMDAS would imply the first answer (5 + (3/x)).
