3x/x = 3
-> 4 + [(x+1)/2x] + (5/x) = (8x + x + 1 + 10)/2x
                                         = (9x + 11)/2x 
                                          = 4.5 + (11/2x)

shiraz14 · Answer

The least common denominator should be 2x

johnkim2330 · Answer

$$ \frac{ 3x }{ x+1 } + \frac{ x+1 }{ 2x } + \frac{ 5 }{ x }$$

shiraz14 · Answer

Or wait ... I think I must have misread your question - did you mean 3x/(x+1)? In that case, the least common denominator is 2x(x+1).
