Question

which equation represents the hanger balance?
9 = y + 4
how can you get y by itself and keep the hanger balanced?
subtract four 1s on both sides.
what is the value of y?
y =
(image of hanger with five 1s on left and y on right, and equation 9 = y + 4 with subtraction of 4 on both sides shown)

Explanation:

Step1: Start with the equation

We have the equation \( 9 = y + 4 \).

Step2: Subtract 4 from both sides

To solve for \( y \), we subtract 4 from both sides of the equation. So, \( 9 - 4 = y + 4 - 4 \).

Step3: Simplify both sides

Simplifying the left side: \( 9 - 4 = 5 \). Simplifying the right side: \( y + 4 - 4 = y \) (because \( 4 - 4 = 0 \), so we're left with \( y \)).

Answer:

\( y = 5 \)
