To determine the correct answer, we will simplify the equation step by step.
The given equation is:
\[ 3(-y + 7) = 3(y + 5) + 6 \]
Let's expand both sides:
1. The left side:
\[ 3(-y + 7) = -3y + 21 \]
2. The right side:
\[ 3(y + 5) + 6 = 3y + 15 + 6 = 3y + 21 \]
Now, the equation can be rewritten as:
\[ -3y + 21 = 3y + 21 \]
Next, let's isolate the terms involving \(y\). We will move \(3y\) to the left side and 21 to the right side:
\[ -3y
