Jul 14, 2016

Making use of the following fact from $\textcolor{b l u e}{\text{laws of logarithms}}$
$\textcolor{red}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} \textcolor{b l a c k}{\log x = \log y \Rightarrow x = y} \textcolor{w h i t e}{\frac{a}{a}} |}}}$
$\Rightarrow 10 - 4 x = 10 - 3 x \Rightarrow x = 0$
