Question

Помгите плиз с уравнениями 86- (14 + х) = 21 37 - (4+х) = 9 (1545+х) : 83 = 70 (90- х) + 60 = 150

Answer 1

86-(14+х)=21
14+х=86-21
14+х=65
Х=65-14
Х=51

Answer 2

86- (14 + х) = 21

14 + х = 86 - 21

14 + х = 65

х = 65 - 14

х = 51

37 - (4+х) = 9

4 + х = 37 - 9

4 + х = 28

х = 28 - 4

х = 24

(1545+х) : 83 = 70

1545 + х = 83 * 70

1545 + х = 5810

х = 5810 - 1545

 х = 4265

(90- х) + 60 = 150

90 - х = 150 - 60

90 - х = 90

 х = 90 - 90

х = 0
