Solve $2+5\ln{x}=21$

\$\begin{array}{rlll}

\textsf{isolate} &\ln{x} &=\dfrac{19}{5} &(1)\\

\textsf{then} & &= &(2)\\

\textsf{then} & &= &(3)\\

\textsf{hence} & &= &(4)

\end{array}$

ok for (2) I presume e thru then calculate for x

just strange to see a fraction as an e exponent

tryin array on these no sure if its better :unsure:
