Question

write an equation that represents the weights on the hanger. 3n + 2 = 8 how can you isolate the term 3n? subtract 2 from both sides. add 2 to both sides. divide both sides by 3. subtract 8 from both sides.

Explanation:

To isolate \( 3n \) in the equation \( 3n + 2 = 8 \), we use the inverse operation of addition (since 2 is added to \( 3n \)). The inverse of adding 2 is subtracting 2. So we subtract 2 from both sides of the equation: \( 3n + 2 - 2 = 8 - 2 \), which simplifies to \( 3n = 6 \). Adding 2 would not isolate \( 3n \), dividing by 3 would isolate \( n \) (not \( 3n \)), and subtracting 8 is not the correct inverse operation here.

Answer:

A. Subtract 2 from both sides.
