The strategy is following
Smaller number subtract from the greater. Result is distance between two numbers
For example you have 3 and 8
8-3-5
5 is the distance between 3 and 8
It also works with the negative numbers, for example 3 and -5
3-(-5)=8

Answer:
See Explanation
Step-by-step explanation:
Given the illustration in the question
Required:
Use deductive reasoning to prove (a)
From your question, you need only the (b) part and this is done as follows;
Step 1: Represent the number with: n
Step 2: Multiply n by 4: 4n
Step 3: Add 10 to (2) above: 4n + 10
Step 4: Divide (3) above by 2: (4n + 10)/2 = 4n/2 + 10/2 = 2n + 5
Step 5: Subtract 5 from (4): 2n + 5 - 5 = n
<em>Hence, the end result is proved to be 2n </em>
<em></em>
<em>Test this with any of the given illustration in (a) part, your answer will always be 2n</em>
