Вычисляем y для x = 2:
\[ y = 0.5 \cdot 2 - 3 = 1 - 3 = -2 \]
Вычисляем y для x = 5:
\[ y = 0.5 \cdot 5 - 3 = 2.5 - 3 = -0.5 \]
Вычисляем x для y = -4:
\[ -4 = 0.5x - 3 \]
\[ 0.5x = -4 + 3 \]
\[ 0.5x = -1 \]
\[ x = -1 : 0.5 \]
\[ x = -2 \]
Вычисляем x для y = 2:
\[ 2 = 0.5x - 3 \]
\[ 0.5x = 2 + 3 \]
\[ 0.5x = 5 \]
\[ x = 5 : 0.5 \]
\[ x = 10 \]
