    I am stuck on how to solve this

    I thought that as per any fraction, remove the denominator so I multiplied both sides by a; and I got....

    x= ab /amk

    Is this right?

    Do you have to get x by itself?
    When you multiply though by a, you only add it to the top. You've added it to the top and bottom.

    2 approaches you can take:

    (i) invert both fractions to start with;

    or

    (ii) multiply both sides by mka to clear all fractions and then rearrange
