Log(base of)2(3x−1)=5 Not sure what to do after I get 31=3x Because I pretty sure you cant have a decimal

This is what you meant right? \[Log_{2}(3x-1) = 5\]

My bad I was looking at your answer. It should be 33 = 3x. You add to get rid of the -1

\[2^{5} = 3x-1 \] \[\frac{ (2^{5}+1) }{ 3 } = x | \frac{ 33 }{ 3 } = 11\]
