I do have a suggestion, actually! Here is the original equation:

 $$2\tan^{-1}{x}=1$$ Divide 2 on both sides $$\tan^{-1}{x}=\frac{1}{2}$$ $$\tan({\frac{1}{2}})=x$$ Evaluate with a calculator.

Now, I am giving you 2 answers because I do not know if you want your answer in degree mode or in radian:

Degree mode:
$$x\approx0.008726867791$$

$$x\approx0.546302489844$$

Solve for x:
2 tan^(-1)(x) = 1

Divide both sides by 2:
tan^(-1)(x) = 1/2

Take the tangent of both sides:
