2. var b = 2;
3. var c = 7;
4. a = a + b;
5. b = a + b;
6. c = a + b;
7. console.log(a);

Step-by-step explanation:

Line 7 - 9

Use console.log to display variable a, b and c to terminal and we will get the result as below

7

9

16

The a is 7 because a = a + b = 5 + 2 = 7

The b is 9 because b = a + b = 7 + 2 = 9

The c is 16 because c = a + b = 7 + 9 = 16
