how about posting the image NOT in the main question?

OpenStudy (danmac0710):

I think there may be an error in this investigation which I am doing from a textbook. I don't know what they mean when they say solve for x, as they have just stated permitted values of 'x', so we have a solution. I think they might mean solve for BC perhaps? Can you please help, it's doing my head in! I need to post an image...

OpenStudy (danmac0710):

Strange.... I posted an image yesterday but it disappeared. Moderated perhaps?
