Question

write an equation that represents the weights on the hanger.

Explanation:

Step1: Calculate left side total

The left side has 3 weights of $n$ and 2 weights of 1, so total is $3n + 2$.

Step2: Calculate right side total

The right side has 8 weights of 1, so total is $8$.

Step3: Set sides equal (balanced hanger)

Since the hanger is balanced, left total = right total.

Answer:

$3n + 2 = 8$
