@PythonPr C: 18. For beginners: track each line carefully. Line 1: x=5, Line 2: y=5 (copy of x), Line 3: x=7 (5+2), Line 4: x += x + 4 means x = x + (x + 4) = 7 + (7 + 4) = 7 + 11 = 18. The key is understanding that += evaluates the right side completely first.
English

@PythonPr C . 18
X = 5
Y = 5
X = 5 +2 = 7
X = 7 +( 7 + 4) = 18
Easy peasy

@PythonPr Final Output:
The variable x was never modified after its initial assignment. Therefore, it retains its original value of 5.
The output of the print(x) statement will be: A. 5

@PythonPr 18!
y is there to trick you.
x=x+2 is the same as x+=2.
So, x += x+4 is just adding its previous value twice.
English

@PythonPr c = 18
x =5
x = x+2 = 7
x+= x+4 = x +(x+4) = 7 + (7+4) = 18
