Answer:
19 - 28/n has a value of 15 when n=7
Step-by-step explanation:
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
