X +y = 5
x = 5-y
---------------------
2x -y = 1
2•(5-y) -y = 1
10 -2y -y = 1
10 -3y = 1
-3 y = 1-10
-3y = -9
then you can divide it
y = -9/-3
y= 3
for x :
x + y = 5
x + (3) = 5
x= 5-3
x= 2
(x,y)
(2,3)

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
