Equation $ e^{2x+1.21} = 114\cdot 4^x $ steps I've done so far.
- $2x + 1.21 = \ln(114) \cdot \ln(4) \cdot x$
- $x = (\ln(114) * \ln(4))/1.21$
I don't think I was allowed to move the $x$ from the right side to the left the way I did.

It should be $2x+1.21=\ln(114)+(\ln 4)x.$ (Recall that if $a$ and $b$ are positive, then $\ln(ab)=\ln(a)+\ln(b)$.)
The rest should not be difficult. The displayed equation is linear in $x$. Bring the $x$ stuff to one side, and everything else to the other side.
