I can only get

x = 1

which is not one of the choices

I would advise graphing this equation and seeing where they cross the axis.

Equivalently, you could graph

and and see where they intersect.

actually that's how i interpreted the question to be since it wasn't clearly written. This is exactly how i saw it written down:



So is there any way that the above question can be "interpreted" to give one of the 4 responses mentioned previously?

as Prove IT suggested to graph it

did graph this and none of answers showed except x = 1 is the only interger value

and got 1/2

its a strange multiple choice

The only answers I can see are 1 and 1/2. Putting it into Maple confirms, as well as another way funky answer. None of these are of course a choice. Something tells me the problem might be written down wrong?
