(2) + (2)
=> 8x - 6y = -46 ———(3)
(1) + (3)
=> 5x + 6y + (8x - 6y) = 20 - 46
=> 13x + (6-6)y = -26
=> 13x + 0y = -26
=> 13x = -26
=> x = -26/13
=> x = -2
=> 5(-2) + 6y = 20
=> 6y = 20 + 10
=> 6y = 30
=> y = 5
x = -2, y = 5 => C

In my opinion, no. Others may think that when you subtract this way, it is much easier. My way to subtract numbers is below:-
Example: 17 - 11
Take the numbers that seem easy to add.
10 - 10 = 0
7 - 1 = 6
6+0 = 6
Now, we know that 17 - 11 = 6
We could have done it this way:-
17
- 11

0 6
