Easiest way to solve these would to be plugging in those solutions and see which ones work

mathmate · Answer

I notice that the first question has only x in the equation, and all four answer have an ordered pair.  Is something wrong, or perhaps I need new glasses?

anonymous · Answer

thats the equations I have

dtan5457 · Answer

Yah, i've noticed that too. maybe there are 2 x values. not sure.

mertsj · Answer

$$\frac{x-11}{x+4}=2-\frac{4}{x}$$
$$\frac{x-11}{x+4}=\frac{2x-4}{x}$$

mertsj · Answer

When you cross multiply you will get a quadratic equation.  As a previous poster suggested, it would be easiest to just substitute the given answers into the equation and see which choice works.
