The Examsolutions method is the way I would do it.

It would be useful if you tell us the exact part of the video where you first didn't understand something.
3. By adding both of the vectors you obtain
Since this vector is in the direction you obtain the expression

Where is just a numerical value. As the force can be of greater magnitude than this vector. By splitting it into i and j components.

Sub one into other to get

so
4. The theory is that the resultant force is found as the vector sum of all the forces acting upon a particle. If a direction is given for the resultant force then it will act in that direction but may be of a different magnitude hence the constant term k.
