\[ 36 : (x \cdot 3 – 15) = 70 - 64 \]
\[ 36 : (x \cdot 3 – 15) = 6 \]
\[ x \cdot 3 – 15 = \frac{36}{6} \]
\[ x \cdot 3 – 15 = 6 \]
\[ x \cdot 3 = 6 + 15 \]
\[ x \cdot 3 = 21 \]
\[ x = \frac{21}{3} \]
\[ x = 7 \]
\[ -24 \cdot (480 : x – 56) = 28 - 124 \]
\[ -24 \cdot (480 : x – 56) = -96 \]
\[ 480 : x – 56 = \frac{-96}{-24} \]
\[ 480 : x – 56 = 4 \]
\[ 480 : x = 4 + 56 \]
\[ 480 : x = 60 \]
\[ x = \frac{480}{60} \]
\[ x = 8 \]
Ответ: x = 7, x = 8
