Solve using elimination:
2x + 3y = 8
x - 3y = 4
2x + 3y = 8
x - 3y = 4
-----------
3x = 12
3x = 12
x = 12 / 3
x = 4
2(4) + 3y = 8
8 + 3y = 8
3y = 0
y = 0

Solve using elimination
9x + 6y = 3
4x - 6y = 20
9x + 6y = 3
4x - 6y = 20
-----------
13x = 23
x=23/13
3(23/13) + 2y = 1
69/13 + 2y = 1
2y = 1 - 69/13
2y = -56/13
y = -28/13
