    Solve\[\frac{12}{7}(x-5)=24+8x\]

    A) \[\frac{-57}{11}\]                              

    B)  \[\frac{57}{11}\]

    C) \[\frac{67}{11}\]                    

    D)  \[\frac{-67}{11}\]

    Correct Answer: A

    Solution :

    \[\frac{12}{7}(x-5)=\frac{24+8x}{1}\] \[\Rightarrow 12(x-5)=7(24+8x)\] \[\Rightarrow \]\[12x-60=168x+56x\] \[\Rightarrow \]\[-60-168=56x-12x\] \[\Rightarrow \]\[-228=44x\] \[\therefore \]    \[x=\frac{-228}{44}=\frac{-57}{11}\]
