can someone explain to me also how to do addition with equations.

Solve the system by addition

5x-3y=13

4x-3y=11

its easy try properly

It's not easy

"It's not easy"

Then how come I found the answer:

x = 2; y = -1, in just five seconds by just looking at the equations? :)

How did you come up with those answers.
