I'll do the first one to get you started





Divide both sides by 3.5.


Take the log of both sides (log can be any base, but I'm using base 10)


Pull down the exponent.


Divide both sides by to isolate x. Note: for some reason, there's this weird gap, so ignore it and pretend it's not there.

So we go from to after solving for x.
