# Variable fraction equations? watch

1. 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?
2. 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.

Sorry, no I am meant to solve the equation for k.
