Question

interactive practice: write and solve one-variable equations
which equation is shown on the hanger?
options: ( n + 4 = 8 ), ( 3 + n = 8 ), ( n = 3 ), ( 4n = 8 )

Explanation:

Step1: Analyze left side of hanger

Left side has 4 \( n \)-weighted blocks, so total is \( 4n \).

Step2: Analyze right side of hanger

Right side has 8 blocks of weight 1, so total weight is 8.

Step3: Set up equation

Since hanger is balanced, left = right: \( 4n = 8 \).

Answer:

\( 4n = 8 \)
