Solve the equation below for x: <br><br> logx+log(x-2)=log(3x)
Ugo [173]

Answer:

x=5

Step-by-step explanation:

Given equation is

\log\left(x\right)+\log(x-2)=\log(3x)

Apply formula: \log A+\log B=\log\left(AB\right)

\log\left(x(x-2)\right)=\log(3x)

\log\left(x^2-2x)\right)=\log(3x)

Since both sides have equal bases so we can drop the log

x^2-2x=3x

x^2-2x-3x=0

x^2-5x=0

x(x-5)=0

Which gives x=0 and x-5=0

or x=0 and x=5

Original problem \log\left(x\right)+\log(x-2)=\log(3x) is not defined at x=0 henc only x=5 is the final answer.
