Question

how can you isolate h?
2h - 12 = 4
+ 12 + 12
2h = 16
add 12 on both sides.
? on both sides.
options: add, subtract, multiply by, divide by

Explanation:

Step1: Analyze the equation after first step

After adding 12 to both sides, we have \(2h = 16\). To isolate \(h\), we need to get rid of the coefficient 2 attached to \(h\).

Step2: Determine the operation

The term with \(h\) is \(2h\), which means \(2\times h\). To undo multiplication, we use division. So we should divide both sides by 2. Looking at the options, the operation is "Divide by" and the number is 2.

Answer:

Divide by, 2
