Конечно! Давайте решим уравнения: 1. \( x - 8 = 72 \) - \( x = 72 + 8 \) - \( x = 80 \) 2. \( x \cdot 5 = 120 \) - \( x = \frac{120}{5} \) - \( x = 24 \) 3. \( 15 \cdot x = 45 \) - \( x = \frac{45}{15} \) - \( x = 3 \) 4. \( 4 \cdot x = 9 + 70 \) - \( 4 \cdot x = 79 \) - \( x = \frac{79}{4} \) - \( x = 19.75 \) 5. \( x + 7 = 20 \) - \( x = 20 - 7 \) - \( x = 13 \) 6. \( 140 : x = 5 \) - \( x = \frac{140}{5} \) - \( x = 28 \) 7. \( x : 4 = 9 \) - \( x = 9 \cdot 4 \) - \( x = 36 \) 8. \( x \cdot (8 + 4) = 15 - 10 \) - \( x \cdot 12 = 5 \) - \( x = \frac{5}{12} \) Надеюсь, это поможет!
