{4x-8y = -3

{2x+ky = 16

I know that the answer is k = -4 but I don't know how to solve to get that answer.

**Reiny**, Wednesday, May 7, 2008 at 7:45amIf the system is inconsistent implies there is no solution.

To have no solution to two linear equations implies that the two lines are parallel, and thus their slopes must be equal.

the slope of the first is 1/2

the slope of the second is -2/k

so -2/k = 1/2

k = -4
