Answer 1

Ответ:

№1

а) x/8 = 5/4

x = (8 * 5) / 4

x = 10

б) 16/17 = x/34

x = (16 * 34) / 17

x = 32

в) 5/9 = 15/x

x = (9 * 15) / 5

x = 27

№2

а) |x| = 5

x = ±5

б) |x - 6| = 8

x - 6 = ±8

x = ±8 + 6

x1 = 14

x2 = -2

в) |2x + 3| = 0

2x + 3 = 0

2x = -3

x = -1,5

г) |4x + 11| = -7

∅

№3

8 / (4/7) = 14
