Question

Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?

6x + 12y = 13

2x + y = -6

x - 2y = 7

8x - 4y = -5

Answer 1

B

Answer 2

how did u get that?

Answer 3

2x + y = -6 (*2) 4x + 2y = -12 ^ this one looks exactly the same like the one in the problem statement it has a different solution even though it has the same amounts of y, x that means there's a contradiction and the system is inconsistent
