    Solve the inequality \[2x-5\le (4x-7)/3?\]

    A)  \[x\in (-\infty ,\,4)\]         

    B)  \[x\in (-\infty ,\,4]\]

    C)  \[x\in (-\infty ,\,8]\]          

    D)  \[x\in (-\infty ,\,-4]\]

    Correct Answer: B

    Solution :

    Given, \[2x-5\le \frac{(4x-7)}{3}\] \[\Rightarrow \] \[6x-15\le 4x-7\] \[\Rightarrow \] \[6x-4x\le -7+15\] \[\Rightarrow \] \[2x\le 8\] \[\Rightarrow \] \[x\le \frac{8}{2}\,\,\,\,\,\Rightarrow \,\,\,\,\,\,x\le 4\] \[\therefore \] \[x\in (-\infty ,\,4]\]
