x:=1 y:=2*x y:=y*x y:=y+4 y:=y*x y:=y+5

Let's break down the operations step by step to understand how the values of x and y change throughout the process.

1. Initialization:

   • \( x := 1 \)
   • \( y := 2 \times x \)
   • Computation: \( y := 2 \times 1 = 2 \)

2. Update y:

   • \( y := y \times x \)
   • Computation: \( y := 2 \times 1 = 2 \)

3. Update y:

   • \( y := y + 4 \)
   • Computation: \( y := 2 + 4 = 6 \)

4. Update y:

   • \( y := y \times x \)
   • Computation: \( y := 6 \times 1 = 6 \)

5. Update y:

   • \( y := y + 5 \)
   • Computation: \( y := 6 + 5 = 11 \)

After performing all the operations, the final values are:

• \( x = 1 \)
• \( y = 11 \)

So, the final result is \( x = 1 \) and \( y = 11 \).
