Start with the given equation
Since the logs have the same base, this means that the arguments are equal. So
Set the inner arguments equal to one another.
Add 2 to both sides
Subtract 8x from both sides
Combine like terms on the left side
Divide both sides by -4 to isolate x
Reduce
So the possible answer is
However, since you cannot take the log of negative number, this means that is not a real solution. So there are no solutions.
