$\begin{eqnarray} \large \color{blue}2^{\color{brown}x} - \color{blue}2^{\color{brown}y} & = & \large 1 \\ \\ \large \color{green}4^{\color{brown}x}- \color{green}4^{\color{brown}y} & = & \large { \frac 5 3} \\ \\ \\ \large {\color{brown}x} - {\color{brown}y} & = & \large \, ? \end{eqnarray}$

Details and Assumptions:

• $$x$$ and $$y$$ are real numbers.
