Solve: -(y + 9) = 8.
Ay = 17
By = -1
Cy = -17
Dy = 1
Answer & Solution
Correct answer: C. y = -17
1. Distribute the negative sign on the left: -(y + 9) becomes -y - 9.
2. The equation is now -y - 9 = 8.
3. Add 9 to both sides: -y equals 17.
4. Divide both sides by -1 to get y equals -17, and checking confirms -(-17 + 9) equals -(-8) equals 8.
