Question 12065
{{{4-(1/x) = 4x}}} we have a fraction. Get rid of this by multiplying both sides, ie every term by x... this gives:


{{{4x - 1 = 4x^2}}}. Collect all terms to one side, to give


{{{4x^2 - 4x + 1 = 0}}}. Now, hopefully factorise:


(2x-1)(2x-1) = 0


so we have 2x-1 = 0
--> 2x = 1
--> x = 1/2
