Question

how can you isolate the term 2h?
2h - 12 = 4
use an inverse operation to get 2h by itself.

Explanation:

Step1: Identify the operation on 2h

The equation is \(2h - 12 = 4\). The term \(2h\) has \(12\) subtracted from it.

Step2: Apply the inverse operation

The inverse of subtraction is addition. So, we add \(12\) to both sides of the equation.
\[

$$\begin{align*} 2h - 12 + 12&= 4 + 12\\ 2h&= 16 \end{align*}$$

\]
By adding \(12\) to both sides, we isolate \(2h\).

Answer:

To isolate \(2h\) in the equation \(2h - 12 = 4\), we use the inverse operation of subtraction (which is addition) and add \(12\) to both sides of the equation. This gives \(2h - 12 + 12 = 4 + 12\), simplifying to \(2h = 16\).
