Question

a) x + 84 = 200 r) x 135 = 49 - 6) 52 + 2x = 136 r) 3x 83 310 = - B) 89 + 4x = 145 A) 835 5x = 140 срочно​

Answer 1

Пошаговое объяснение:

х + 84 = 200

х = 200 - 84

х = 116

52 + 2х = 136

2х = 136 - 52

2х = 84

х = 84 : 2

х = 42

89 + 4х = 145

4х = 145 - 89

4х = 56

х = 56 : 4

х = 14
