I will apply PEMDAS to answer. PEMDAS = operations within Parentheses, E = Exponentiation, MD = Multiplication or Division, and AS = Addition or Subtraction. If MD both occur or AS both occur, then operations done from left to right.
There is no P or E in the statement, but the comma implies the division is done after operations ahead of the comma are completed.
Let X be the number. I read the problem as equivalent to
4X + 6
-2
