Well its easy mean search a video in YouTube
there are two types for systems of question:
The method for elimination
The method for substitution

The elimination only that u have to do is found x or y hat are the sam,e number with different symbols ↓↓like this↓↓

- 7y + 3x = 45
  7y + 12x = 33

the y is cancel and... u know the process..
But the method for substitution is different u only need to put the y en the problem and that's it, and when u found the valor of x u can solve for y ↓↓like this↓↓  

4x - 2y = 24
y = x - 5

4 (x - 5) = 24
4x - 20 = 24
     +20  +20
4x = 44
4x/4 = 44/4
x = 11
