You would first move the 6 onto the other side by adding it. Then you would end up doing -3+6 which is 3. Then your equation will look like: 5/k=3. You would then do opposite operation again to the 5 this time. You do the opposite of dividing, so multiplying. You multiply the 5 on both sides which you would end up doing 5 x 3 which is 15. Your equation will then be looking like k=15. To check if you did it right, just simply plug in the 15 as k. So the equation to check should look like this: 5/15-6=3. Solve it, and you should end up as the answer being equal to 3.
