The given inequality is


10-4x>2

First, we subtract 10 from each side.


\begin{gathered} 10-10-4x>2-10 \\ -4x>-8 \end{gathered}

Then, we divide the inequality by -4.


\begin{gathered} (-4x)/(-4)<(-8)/(-4) \\ x<2 \end{gathered}

Hence, the solution is all real numbers less than 2.

Therefore, Tarik's solution is not correct because he did not reverse the inequality.

The first option is correct.
