Answer :

Edmund
[tex]\frac{7}{8}h-\frac{5}{8}=2[/tex]

[tex]8(\frac{7}{8}h-\frac{5}{8})=8(2)[/tex]

[tex]7h-5=16[/tex]

[tex]\frac{7h}{7}=\frac{21}{7}[/tex]

[tex]h=3[/tex]
Lilith
[tex] \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 [/tex]
