\[ -3 = \frac{1}{2}x + 3 \]
\[ \frac{1}{2}x = -3 - 3 \]
\[ \frac{1}{2}x = -6 \]
\[ x = -6 \cdot 2 \]
\[ x = -12 \]
\[ -1 = \frac{1}{2}x + 3 \]
\[ \frac{1}{2}x = -1 - 3 \]
\[ \frac{1}{2}x = -4 \]
\[ x = -4 \cdot 2 \]
\[ x = -8 \]
\[ 0 = \frac{1}{2}x + 3 \]
\[ \frac{1}{2}x = -3 \]
\[ x = -3 \cdot 2 \]
\[ x = -6 \]
\[ \frac{1}{2} = \frac{1}{2}x + 3 \]
\[ \frac{1}{2}x = \frac{1}{2} - 3 \]
\[ \frac{1}{2}x = \frac{1}{2} - \frac{6}{2} \]
\[ \frac{1}{2}x = -\frac{5}{2} \]
\[ x = -\frac{5}{2} \cdot 2 \]
\[ x = -5 \]
\[ 1 = \frac{1}{2}x + 3 \]
\[ \frac{1}{2}x = 1 - 3 \]
\[ \frac{1}{2}x = -2 \]
\[ x = -2 \cdot 2 \]
\[ x = -4 \]
\[ 3 = \frac{1}{2}x + 3 \]
\[ \frac{1}{2}x = 3 - 3 \]
\[ \frac{1}{2}x = 0 \]
\[ x = 0 \]
Ответ: x = -12, -8, -6, -5, -4, 0
