Question 111002: 4. Determine if the following system of equations is independent, dependent, or inconsistent:
–7x – 5y = –4
–35x – 25y = 13
A) Independent
B) Dependent
C) Inconsistent
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Determine if the following system of equations is independent, dependent, or inconsistent:
–7x – 5y = –4
–35x – 25y = 13
If you multiply thru the 1st equation by 5 you get:
-35x -25y = -20
----------------
Do you see how "inconsistent" that is with the 2nd equation??
How could the same expression equal 13 and also equal -20 ??
The system is inconsistent.
A) Independent
B) Dependent
C) Inconsistent
