How to solve symbolic equation with double coefficients in matlab?

Question

I have quadratic equation 1/x = 1/(a-x) + 1/(3*a -x)

I want to solve it in matlab:

solve('1/x=1/(a-x)+1/(3*a-x)', 'x')
ans =
 (4/3+1/3*7^(1/2))*a
 (4/3-1/3*7^(1/2))*a

Is there any way to solve equation with float coefficient? Like

ans = 
  2.215250437021530*a
  0.451416229645136*a

Answer 1

Apparently, double(ans) should convert it for you.
