Find a common multiplier then divide ex. 21/27 = 7/9
If i understood the question right, you're trying to find the value when h = -2. If that's true so here is how it's done:

First, apply the distributive property to the left side of the inequality. Multiply each of the two numbers inside the parentheses by 6 and then add those products. Next, subtract -24 from both sides. Then, to get \begin{align*}x\end{align*} by itself on one side of the inequality, you need to divide both sides by 6.
