Ay = 3
By = -27
Cy = -3
Dy = 27
Answer & Solution
Correct answer: C. y = -3
1. Simplify the left side: 14 minus 23 equals -9.
2. Simplify the right side by combining like terms: 12y minus 4y minus 5y equals 3y.
3. The equation is now -9 equals 3y.
4. Divide both sides by 3 to get y equals -3, and checking confirms 12(-3) - 4(-3) - 5(-3) equals -9.
