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 \( y = 11 \).
