    Ok this is easier to factor Try that one instead All I did was to multiply by the LCD to get rid of all of the fractions

    I also could have use 36 but then I would have to do more math LCD means Least common denominator think of what you would have chosen for a common denominator if you had 1/2 + 1/3 + 1/6 would you have picked 6 as well?

    Anytime you have fractions try to get rid of them using LCD

    same concept except within algebra whenever you get confused just write your numbers out to the side. I would have focused on 1/2, 1/3, and 1/6

    But in algebra if you decide to distribute a number, you must distribute it to all terms.
