Question

which equation represents the hanger balance?
options:
y = 4
1 = y
9 = y - 4
9 = y + 4

Explanation:

Step1: Count left side total

Left side: $y + 1 + 1 + 1 + 1 = y + 4$

Step2: Count right side total

Right side: $1+1+1+1+1 + 1+1+1+1 = 9$

Step3: Set sides equal

Since the hanger is balanced, left = right.
$9 = y + 4$

Answer:

$9 = y + 4$
