Answer:
h = E/mg
Step-by-step explanation:
When we want to find out the multiplier, we should devide the product by the others known factors
You just need to divide both sides by mg:
[tex]E=mgh \iff \dfrac{E}{mg} = \dfrac{mgh}{mg}[/tex]
This simplifies mg on the right side:
[tex]\dfrac{E}{mg}=h[/tex]
thus solving the equation for h
