Question

write an equation that represents the weights on the hanger.

Explanation:

Step1: Analyze left side weights

Left side has 2 \(a\) weights and 1 weight of 1, so total weight is \(2a + 1\).

Step2: Analyze right side weights

Right side has 9 weights of 1, so total weight is \(9\).

Step3: Set equal (hanger balanced)

Since hanger is balanced, left = right: \(2a + 1 = 9\).

Answer:

\(2a + 1 = 9\)
