Question

Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?
A:6x + 12y = 13
B: 2x + y = -6
C:x - 2y = 7
D:8x - 4y = -5

Answer 1

I am not sure the definition of causing inconstitent-indipendent system.

Answer 2

it mean that is is the only one that is not correct. so check the others and check if you get to the one that is different.

Answer 3

Yeh.. but how do I tell which one is a inconstitent-indipendent system?

Answer 4

compare it to 4x+2y=9 one of it must be not consistent which mean it is changed

Answer 5

Would it be D?

Answer 6

4x+2y is (an obvious) multiply of 2x+y

Answer 7

"multiple" I meant.
