Question

fill in the parts - whole model for the following equation.
$2 - (\underline{quadquad}) = -7y$

| 2 |

$-7y$

$\boxed{\quadquad}$

Explanation:

Step1: Let the unknown be \( x \)

The equation is \( 2 - x = -7y \).

Step2: Solve for \( x \)

We can rewrite the equation as \( x = 2 + 7y \) (by adding \( x \) to both sides and adding \( 7y \) to both sides, or by rearranging the subtraction formula: if \( a - b = c \), then \( b = a - c \), here \( a = 2 \), \( c = -7y \), so \( b = 2 - (-7y)=2 + 7y \)).

Answer:

\( 2 + 7y \)
