Explain how the story of theme “those who sacrifice for each other are the wisest”.

Explanation: Those who sacrifice are said to be the wisest since these people have offered more to the people they care about rather than thinking about themselves. True wisdom can be found in the love for the recipient regardless of the materials they have given. It is through giving and sacrifice that they understand more about the person and, most especially, themselves.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
