    Sir im doing some revision on solving equations and i can’t answer the fraction equation:
    3x+9/3 – 2x+4/5 = 4
    Please can you explain how to answer this question?

    Hi Lily,

    Are those dividing lines under two terms? ie is it

    (3x + 9)/3 – (2x + 4)/5 = 4

    If so, multiply every term by 15 to get rid of the denominators, then solve in the normal way.

    Yeah, what she said ;-)

    15 is LCM of 3 and 5, so it becomes [15 * (3x+9) / 3] – [15 * (2x +4)5] = 60

    And that will then go to 5(3x+9) – 3(2x+4) = 60

    OK?
