Answer:
3. x + 3y = 6
2x - 3y = 12
----------------------
3x = 18
x = 6
taking first equation
x + 3y = 6
6 + 3y = 6
3y = 0
y = 0/3
y = 0
__________________________________________________________
7. 2x - y = 2
4x - y = 4
multiply second equation with +1
2x - y = 2
4x + y = 4
-------------------
6x = 6
x = 1
taking second equation
4x - y = 4
4 - y = 4
y = 0
