Пошаговое объяснение:

6) 90 + 8y = 154
8y = 154 - 90

8y = 64

y = 64 : 8

y = 8

7) 120*(x - 19) = 6

120x - 2280 = 6

120x = 6 + 2280

120x = 2286

x = 2286 : 12

x = 19,05

8) 48 + y : 6 = 95

y : 6 = 95 - 48

y : 6 = 47

y = 47 * 6

y = 282

9) 8x + 7x - x = 42

14x = 42

x = 42 : 14

x = 3

10) 24y - 12y + 5y - 17 = 0

17y - 17 = 0

17y = 17

y = 17 : 17

y = 1

Answer 2

Пошаговое объяснение:

90 + у*8 = 154

90 + 8у = 154

8у = 154 - 90

8у = 64

у = 64 : 8

у = 8

120(х - 19) = 6

120х - 2280 = 6

120х = 6 + 2280

120х = 2286

х = 2286 : 120

х = 19,05

48 + у : 6 = 95

у : 6 = 95 - 48

у : 6 = 47

у = 47 * 6

у = 282

8х + 7х - х = 42

14х = 42

х = 42 : 14

х = 3

24у - 12у + 5у - 17 = 0

17у - 17 = 0

17у = 17

у = 17 : 17

у = 1
