To solve these equations, we first need to isolate the variables.

1) 5834 - b = 5816
5834 - 5816 = b
b = 18

2) 314 (9072 / d) = 15072
314 (9072 / d) = 15072
9072 / d = 15072 / 314
9072 = (15072 d) / 314
9072 314 = 15072 * d
2850048 = 15072d
d = 189.16

Therefore, the solutions are:
b = 18
d = 189.16
