1. Реши уравнения: X + 19 = 42 C - 28 = 70 54 + X = 82 У * 42 = 84 17 - Y = 9 76 : X = 2

1. Решение уравнений:

• X + 19 = 42
  X = 42 - 19
  X = 23
• 54 + X = 82
  X = 82 - 54
  X = 28
• 17 - Y = 9
  Y = 17 - 9
  Y = 8
• C - 28 = 70
  C = 70 + 28
  C = 98
• Y * 42 = 84
  Y = 84 / 42
  Y = 2
• 76 : X = 2
  X = 76 / 2
  X = 38

Ответ: X = 23, X = 28, Y = 8, C = 98, Y = 2, X = 38
