Answer 10

wait I think I read the problem wrong: is it (1/2) x + (1/4)x = 16 or is it 1/(2x) + 1/(4x) = 16... note there is a big difference

Answer 11

If it is the first case (as I now suspect) try multiplying the whole equation by 4

Answer 12

D

Answer 13

So when you multiply the equation by 4 do you get:
\[4( \frac{1}{2}x + \frac{1}{4} x = 16) \ \ \ \ \rightarrow \ \ \ \ 2x+x=16*4\]
