a see-saw has a total length of 4m and is pivoted in the middle. A child of weight 400 N sits 1.4m from the pivot. A child of weight 300 N sits 1.8m from the pivot on the other side. A parent holds the end of the see-saw on the same side as the lighter child. work out the magnitude and direction of the force the parent must exert to hold the see-saw level.

Can someone please answer this with clear explanation and/or steps shown.
