(A)

Explanation:

This system of equations will no solution if they have the same slope and only differ in the y-intercept values. So let's rewrite the two equations into their slope-intercept forms:


y = (3)/(h-2)x + 5


y = (8)/(h)x + (5)/(h)

For them to have no solution, their slopes must equal each other:


(3)/(h-2) = (8)/(h) \Rightarrow 3h=8h-16

or


h = (16)/(5)

Putting this value into our system of equations, we get


y = (5)/(2)x + 5


y = (5)/(2)x + (25)/(16)

This is a system of equations consisting of two parallel lines and as such, do not intersect and so, no solution.
