Final answer:

The given expression involves multiplication and subtraction. By setting up an equation and solving for x, we find that the input is 16.5.

Step-by-step explanation:

The given sequence of operations is not clear. However, based on the given information, we can deduce the following:

  1. The expression x 4 can represent the multiplication of x by 4.
  2. The expression - 9 can represent the subtraction of 9 from the previous result.
  3. Finally, the expression output = 57 represents the final result.

Using these deductions, we can set up the equations:

x * 4 - 9 = 57

Now, we can solve for x by performing the inverse operations in reverse order:

  1. Add 9 to both sides to isolate the multiplication:
  2. x * 4 = 66
  3. Divide both sides by 4 to solve for x:
  4. x = 16.5
  5. The input, therefore, is 16.5.
