The given equation is
[tex]G(h+\frac{2}{3})=1_{}[/tex]First, we divide both sides by G.
[tex]\frac{G}{G}(h+\frac{2}{3})=\frac{1}{G}\Rightarrow h+\frac{2}{3}=\frac{1}{G}[/tex]Then, we subtract 2/3 from each side.
[tex]h+\frac{2}{3}-\frac{2}{3}=\frac{1}{G}-\frac{2}{3}\Rightarrow h=\frac{1}{G}-\frac{2}{3}[/tex]
