Question

1. -2(x + 7) = 28

(a) if your answer is x = -21 draw the following nose.
(b) if your answer is x = 21 draw the following nose.

Explanation:

Step1: Divide both sides by -2

To isolate the term with \( x \), we divide both sides of the equation \(-2(x + 7)=28\) by \(-2\).
\(\frac{-2(x + 7)}{-2}=\frac{28}{-2}\)
Simplifying both sides, we get \( x + 7=-14 \).

Step2: Subtract 7 from both sides

To solve for \( x \), we subtract 7 from both sides of the equation \( x + 7=-14 \).
\( x + 7-7=-14-7 \)
Simplifying both sides, we find \( x=-21 \).

Answer:

Since the solution is \( x = -21 \), we follow part (a) and draw the nose associated with \( x=-21 \).
