Hi,I recently encountered some peculiar behaviour when solving an inequality. For context this occurred when working on a solution for a manufacturing client - essentially if a certain term is ever going to be less than one we need to be prepared.The issue is that it seems to be possible to produce an incorrect result without an obvious mistake. The expression is[1 - 8/(c+1)] / [ 8/d+1 8/c+1] > 1Solving this one can get to the answer d > 7 without any obvious mathematical violations but this is clearly incorrect as c = 7 equates the expression to 0 and so must feature in the conditions.Is anyone aware of what might be going on here?
