Answer:
(a) i and ii: 2b-2 = b+b-2
(b) i and iii: c+d = d+c
(c) ii and iii: a + 2b - 1 = a+b-1+b
(d) i and iii: x+(y-z) = x-(z-y)
(e) ii and iii: (a-1)² = (1-a)²
(f) i and ii: 3a-b-1-1 = 3a+b-2-2b

Answer:
The number is 38,478
Step-by-step explanation:
* Lets explain how to find the number
- The number is 5-digit
* Ones ⇒ the last digit
* Tens
* Hundreds
* Thousands
* Ten thousand
- The ones digit is the same as the last digit of last year's calendar year
∵ The last year is 2018
∴ The last digit is 8
∴ The ones digit is 8
- The ones digit is the same as the thousands digit
∵ The ones digit is 8
∴ The thousands digit is 8
- The ten thousands digit is five less than the thousands digit
∵ The thousands digit is 8
∴ The ten thousands digit is 5 less than 8
∵ 8 - 5 = 3
∴ The ten thousands digit is 3
- The last two digits sum to 15
∵ The last two digits are ones and tens digits
∵ The ones digit is 8
∵ 15 - 8 = 7
∴ The tens digit is 7
- There is one 4 in the number
∵ The hundreds digit is empty
∴ The hundreds digit is 4
* <em>The number is 38,478</em>
