The initial equation is:


3(x-4)-5=x-3

Now we can distribute the 3 into the parenthesis so:


3x-12-5=x-3

Now we move all variable to the left of the equation and the constants to the right so:


3x-x=-3+12+5

Finally we simplify so:


\begin{gathered} 2x=14 \\ x=(14)/(2) \\ x=7 \end{gathered}

So the answer is C) x = 7
