    subtract 18 from 52 then take the natural log of both sides to solve for it.

    I think the solution is \[\log_{6} 34=3x-5\]

    And then I'm assuming you know how to solve for x.

    6^3x-5=52-18 6^3x-5=34 log6^3x-5 =log 34 3x-5log6=log 34 (3x-5) 0.7781=1.5314 [use calculator to find the value of lof 6 and log 34] 3x-5=1.97 3x=6.97 x=2.32
