4. Реши уравнения: 40: X = 8 X-24=56 5 * У = 35 18 + У = 30 40+ X = 40 + 2 X*6=9*4

Решение:

Решаем уравнения:

1. \( 40 : X = 8 \)
   \( X = 40 : 8 \)
   \( X = 5 \)
2. \( X - 24 = 56 \)
   \( X = 56 + 24 \)
   \( X = 80 \)
3. \( 5 * Y = 35 \)
   \( Y = 35 : 5 \)
   \( Y = 7 \)
4. \( 18 + Y = 30 \)
   \( Y = 30 - 18 \)
   \( Y = 12 \)
5. \( 40 + X = 40 + 2 \)
   \( 40 + X = 42 \)
   \( X = 42 - 40 \)
   \( X = 2 \)
6. \( X * 6 = 9 * 4 \)
   \( X * 6 = 36 \)
   \( X = 36 : 6 \)
   \( X = 6 \)

Ответ: X = 5, X = 80, Y = 7, Y = 12, X = 2, X = 6.
