Помогите с домашкой математика 5 класс​

Answer 1

1 . 29 X - 15 x + 16= 100 задание номер 472

14 X + 16=100

14 X = 84

X = 84:14

X = 6

2 . 11 y + 32 y - 127 =45

43 y - 127 =45

43 y= 127 + 45

43 y= 172

y=4

3. 15z+8z-59=102

23z - 59=102

23 z =102+59

23 z= 161

z=161:23

z=7

4. 9t+4t- 286 = 0

13t- 286 =0

13t =286+0

13t = 286

t =286:13

t =22

5. 14 x + 9 x + 88 =272

23 x + 88 = 272

23 x = 272 - 88

23x = 184

x = 184: 23

X =8

6. 25 x - 16 x + 54 = 162

9 x + 54 = 162

9 x = 162 - 54

9x = 108

X = 108 : 9

X = 12
