That's right. You can go further than that seeing that the right hand member is -1%2F2. You can then say, the LCD is highlight_green%282x%28x-7%29%29. You would then solve for x by first multiplying the right and left members by 2x%28x-7%29. Doing so and simplifying will clear the denominators, and you continue solving for x.


(Do not capitalize a variable unless it is defined that way in the problem; in which case always capitalize it in the problem. highlight_green%28X%3C%3Ex%29.)
