can check answers by substituting back into original equation.

x = ln2/ln3 does not satisfy the original equation.
x = -ln2/ln3 satisfies the original equation.

in the working on the left, mistake is in 4th line from bottom. the "+ln3" should be "-ln3" due to the '-' sign outside the bracket in the previous line.
