44. Реши уравнения. c * 9 = 130 + 140 x : 8 = 200 - 120 164 - x = 720 : 9

**Решение уравнений:** 1. \[c \cdot 9 = 130 + 140\] \[c \cdot 9 = 270\] \[c = 270 : 9\] \[c = 30\] 2. \[x : 8 = 200 - 120\] \[x : 8 = 80\] \[x = 80 \cdot 8\] \[x = 640\] 3. \[164 - x = 720 : 9\] \[164 - x = 80\] \[x = 164 - 80\] \[x = 84\] **Ответы:** \(c = 30\), \(x = 640\), \(x = 84\)
