Answer

$x=\dfrac{2}{35}$

Work Step by Step

Apply the quotient rule to have: $\log_6{\left(\frac{x+2}{x}\right)}=2$ RECALL: $\log_a{b}=x \longrightarrow a^x=b $ where $b\gt0$ Use this rule in converting the equation to its equivalent exponential equation to have: $6^2=\dfrac{x+2}{x} \\36=\dfrac{x+2}{x} \\36(x)=x+2 \\36x=x+2 \\36x-x=2 \\35x=2 \\x=\dfrac{2}{35}$
