Исходное уравнение:
\[ -3.2(-5x + 0.5) - 12x = 6 - (0.5x - 5) \]
\[ (-3.2) \cdot (-5x) + (-3.2) \cdot (0.5) - 12x = 6 - (0.5x - 5) \]
\[ 16x - 1.6 - 12x = 6 - (0.5x - 5) \]
\[ 16x - 1.6 - 12x = 6 - 0.5x + 5 \]
\[ (16x - 12x) - 1.6 = 6 - 0.5x + 5 \]
\[ 4x - 1.6 = 6 - 0.5x + 5 \]
\[ 4x - 1.6 = 11 - 0.5x \]
\[ 4x + 0.5x - 1.6 = 11 \]
\[ 4.5x - 1.6 = 11 \]
\[ 4.5x = 11 + 1.6 \]
\[ 4.5x = 12.6 \]
\[ x = \frac{12.6}{4.5} \]
\[ x = 2.8 \]
Ответ:
x = 2.8
