Answer:
3
Step-by-step explanation:
2x + 2y = 4
dividing both sides by 2,we get
x + y = 4,which is the same line A
so this set of equations has infinitely many solutions as they intersect each other at infinite points i.e they overlap eachother

Answer:
12
Step-by-step explanation:
So first, when z is divded by 6 we get 4 left. 
So an example for z could be 24. 
(24 / 6 = 4)
When z is divded by 2, it would be 12
24 / 2 = 12
