\[ 10x = 3y + 0.1 \]
\[ x = \frac{3y + 0.1}{10} \]
\[ 15(\frac{3y + 0.1}{10}) + 4y = 2.7 \]
\[ \frac{45y + 1.5}{10} + 4y = 2.7 \]
\[ 4.5y + 0.15 + 4y = 2.7 \]
\[ 8.5y = 2.7 - 0.15 \]
\[ 8.5y = 2.55 \]
\[ y = \frac{2.55}{8.5} \]
\[ y = 0.3 \]
\[ x = \frac{3(0.3) + 0.1}{10} \]
\[ x = \frac{0.9 + 0.1}{10} \]
\[ x = \frac{1}{10} \]
\[ x = 0.1 \]
Ответ: x = 0.1, y = 0.3
