Jan 23, 2016

Subtract $4$from both sides of the equation and then divide both sides by $3$, to get
$\textcolor{w h i t e}{\text{XXX}} h = \frac{2}{3}$

Explanation:

$3 h + 4 = 6$

$\Leftrightarrow 3 h + 4 \textcolor{b l u e}{- 4} = 6 \textcolor{b l u e}{- 4}$

$\Leftrightarrow 3 h = 2$

$\Leftrightarrow \frac{3 h}{\textcolor{red}{3}} = \frac{2}{\textcolor{red}{3}}$

$\Leftrightarrow h = \frac{2}{3}$
