Question

what equation does the hanger show now?
$x = 3$
$x = 7$
$x + 3 = 4$
$x + 3 = 7$

Explanation:

Step1: Count left side total

Left side: $x + 1 + 1 + 1 = x + 3$

Step2: Count right side total

Right side: $1+1+1+1+1+1+1 = 7$

Step3: Set sides equal

Since the hanger is balanced, left = right.

Answer:

$x + 3 = 7$
