Question

A:=3 b: =a+8 a:=21-b*a b:=b*(a+1)

Answer 1

b: = 11;

a: = 21 - 11*3=21-33=-12;

b:=11(-12+1) = -121.

Answer 2

b: 3+8=11

a: 21-11*3=21-33=-12

b: 11*(-12+1)=11*(-11)=-121

Answer 3

To compute the final values of variables A and B, let's follow the instructions step by step:

1. A := 3 Set variable A to 3.

2. B := A + 8 Since A was set to 3 in the previous step, B will be calculated as follows: B = 3 + 8 B = 11

3. A := 21 - B * A Now, A will be recalculated using the current values of A and B: A = 21 - 11 * 3 A = 21 - 33 A = -12

4. B := B * (A + 1) Finally, update the value of B: B = 11 * (-12 + 1) B = 11 * (-11) B = -121

So, the final values of variables A and B are: A = -12 B = -121
