The goal of this problem is to create an equation that would allow you to calculate h directly from the given equation. To accomplish his, use inverse operations as follows:
d = 1/5 h w
Multiply both sides of the equation by the reciprocal of 1/5 or 5:
5d = 1/5 h w * 5
5d = h w
Now divide both sides by w:
5d/w = h w /w
5d/w = h
So you can write that h = 5d/w
dh = 1/
