Question

write an equation to represent this hanger diagram.
the left side of the hanger has three groups, each group consists of a pentagon labeled y and a square labeled 2. the right side of the hanger has a rectangle labeled 15.
there is a formula box: \square (\square + \square ) = \square
below the formula box are the numbers and letter: 6, 2, 15, 3, y

Explanation:

Step1: Identify equal side weights

Left side: 3 groups of $(y + 2)$
Right side: 15

Step2: Set up equality equation

$3(y + 2) = 15$

Answer:

$3(y + 2) = 15$
