Verified Answer :

Edmund

\(\frac{7}{8}h-\frac{5}{8}=2\)

\(8(\frac{7}{8}h-\frac{5}{8})=8(2)\)

\(7h-5=16\)

\(\frac{7h}{7}=\frac{21}{7}\)

\(h=3\)

Lilith

\(\frac{7}{8}h-\frac{5 }{8}=2 \ \ |+\frac{5}{8}\\ \\\frac{7}{8}h=2+\frac{5 }{8}\\ \\\frac{7h}{8}=\frac{16}{8}+\frac{5 }{8} \\ \\\frac{7h}{8}=\frac{21}{8} \ \ / *8\\ \\ 7h=21 \ \ /:7 \ \ \\ \\h=\frac{21}{7}\\ \\h=3\)
