  1. Уравнения 5 класс Составила Мордовских Надежда Васильевна, Учитель математики МБОУ Сарасинской СОШ

  2. Упрости (925 + х) - 325= =(925 – 325) + х= =600 + х

  3. Упрости 619 – (219 + х)= =619 – 219 – х= =400 - х

  4. Упрости 1.412 – (х + 312) 2.(х + 37) – 27 3.(128 + х) – 28 4.649 – (х + 549)

  5. Проверь себя • 100 – х • х + 10 • 100 + х • 100 - х

  6. Реши уравнение • (257 – х) + 124 = 149 257 – х = 149 – 124 257 – х = 125 х = 257 – 125 х = 132 ОТВЕТ: 132

  7. II способ (257 – х) + 124 = 149 257 + 124 – х = 149 381 – х = 149 х = 381 – 149 х = 232 Ответ: 232

  8. Реши А) 165 – (х + 112) = 37 Б) 44 + (х – 85) = 105 В) 243 – (х + 83) = 112 Г) (135 + х) – 37 = 108

  9. Проверь себя • 16 • 146 • 48 • 10
