Answer

Does not make sense.

Work Step by Step

No. To solve the first equation, you would use the definition of logarithms: if $ y=\log_{b}x $ then $ x=b^{y}$) The next step would be $ 3x+1=10^{5}\qquad $, etc. The second equation is solved by applying the one-to-one property of logarithmic functions: if $\log_{b}M=\log_{b}N,$ then $ M=N $ So the next step is $ 3x+1=5\qquad $, etc.
