Dependent
Step-by-step explanation:
and
Lets solve the second equation for y and then substitute it in first equation
Subtract 6x on both sides
Divide by 2 on both sides
Now we plug it in first equation for y
Add 3x on both sides
Both sides are same, they are equal. the system has infinite solutions.
They are said to be dependent
