Alissa is currently a teacher in the San Francisco Bay Area and Brightstorm users love her clear, concise explanations of tough concepts
When you have logs with different bases and x's in two places, you need to get all of the x's on one side of the equation any way you can. From there, factor out an x, and use division to get x isolated. These can be very difficult to type into your calculator correctly, so be extremely precise with use of parentheses and consider breaking it into parts to evaluate separately.
