Question

use the hanger diagram to solve for the value of ( x )?

Explanation:

Step1: Set up equation from hanger

The hanger shows $3z + 7 = 19$

Step2: Subtract 7 from both sides

$3z + 7 - 7 = 19 - 7$
$3z = 12$

Step3: Divide by 3 on both sides

$\frac{3z}{3} = \frac{12}{3}$
$z = 4$

Answer:

$z = 4$
