Answer:
The system of equations is not independent (i.e. dependent)
Step-by-step explanation:
We see that in the system of equations
3x + 6y = 12 ............(1)
x + 2y = 4.................(2)
equation (1) is exactly the same as 3 times of equation (2).
When graphed, both lines will coincide.
Therefore the system of equations is not independent (i.e. dependent)
