$\displaystyle \frac{20}{3x} = 4$

$\displaystyle 20 = 4 \times 3x$

$\displaystyle 20 = 12 x$

$\displaystyle \frac{20}{12} = x$

$\displaystyle x = 1,666....$

I guess you made a mistake when setting x = 1,666... into your equation.

Remember x is actually equal to 1,6666666666666666... into infinity :)

Rather try setting $\displaystyle \frac{5}{3}$ into it, which is equal to 1,666...
