Answer:

19 - 28/n  has a value of 15 when n=7

Step-by-step explanation:

Expression are

43 - 5n

3n - 5

6n - 28

19 - 28/n

when n = 7

43 - 5n = 43 - 5 * 7 = 43 - 35 = 8  ≠ 15

3n - 5 = 3*7 - 5 = 21 - 5 = 16 ≠ 15

6n - 28 = 6 * 7 - 28  = 42 - 28 = 14  ≠ 15

19 -  28/n = 19  - 28/7  = 19  - 4 = 15 = 15

19 - 28/n has a value of 15 when n=7
