How do I Solve for m: W = mgH – mgh?

Question

????

Answer 1

reverse distribute the terms as though mg was a coeficiant

mgH-mgh  = mg(H-h)

now that you only have one term with m its easy just divide

W/((H-h)+g)) = m

Answer 2

W = m(gH - gh) = mg (H-h)

m = W/(g(H-h))

Answer 3

W = mgH – mgh

W = m(gH – gh)

m = W/(gH -- gh)
