Solving for x

I'm lost here:

11.6 = (14x + 60)/(x+6)

how can I find x with this equation ??
Any help appreciated !

$11.6(x+6) = 14x+60$

distribute the left side, combine like terms, isolate x to solve

remember $x \ne -6$

$\displaystyle 11.6 = \dfrac{14x+60}{x+6} ,\ \ the\ denominator\ can\ not\ be\ zero : \ \ x+6 \ne 0 \ \Longrightarrow x \ne -6
\\\;\\
\dfrac{116}{10}=\dfrac{14x+60}{x+6},\ \ then
\\\;\\
116(x+6) = 10(14x+60)$
