    so all the denominators have to be equal. 2x can be our common denominator. Multiply the 15/2 by 2x. The 2 gets cancelled with the 2 on the bottom and 15 gets multiplyed by x. The last one should become 30x for the same reasons. It has no bottom value but one, so it must be multiplyed by all. The first value cancels 2x out since it has it as its denominator.

    oh okay so now you just subtract 15x from both sides and then divide(:

    when you subtract 15x from 30x, you get 15x Then divide 5 by 15. You can simplify 5/15 to 1/3. Which is your answer.
