Work it like a normal algebra problem to get ln x on one side. Then use a calculator or log tables.

Explanation:

Until you get to the actual logarithm the math is the same as for any algebra equation.

2 − 6xxln(x) = 1026×ln(x)=10 ; -6ln(x) = 86ln(x)=8 ; ln(x) = -(4/3)ln(x)=(43)

NOW we take the antilog, inverse, or exponential of both sides:

e^(ln(x)) = e^(-(4/3))eln(x)=e(43) ; x = 0.264x=0.264

CHECK:
2 − 6xxln(x) = 1026×ln(x)=10 ; 2 − 6ln(0.264) = 1026ln(0.264)=10

2 − 6(-1.33) = 1026(1.33)=10 ; 2 - (-8) = 102(8)=10 ; 10 = 1010=10 CORRECT!
