To all Franciscan,
Ya'll need to know these thingy in order to pass ur Additional Mathematics in SPM and STPM
my "SPM" means Sijil Pergi Mati and "STPM" means Sijil Terus Pergi Mati
Haha..
Simultaneous Equations
Example 1 :
Thank You = Good ------ 1
No Thank You = Bad --------- 2
Subtitute 1 into 2
No Thank You = Bad
No (Good) = Bad
No Good = Bad ##
------------------------------------------------------------------
See.. It Works!!
Example 2 :
Husband + Wife = Family - 1
Husband + Sob = Family - 2
Husband + Daughter = Family - 3
±Family = Daughter (± Son) + Father + Mother - 4
Subtitute 1 into 2
Husband + Son = Family
Husband + Son = Husband + Wife --- 5
From 3
Husband + Daughter = Family
Husband = Family - Daughther --- 6
Subtitute 6 into 5
Husband + Son = Husband + Wife
Family - Daughter + Son = Family - Daughter + Wife
Son = Wife ---- 7
From 4
±Family = Daughter (± Son) + Father + Mother
±Son = Daughter ±Family + Father + Mother --- 8
Subtitute 8 into 7
Son = Wife ---- 7
±(Daughter ±Family + Father + Mother) = Wife
+Daughter + Family + Father + Mother = Wife
- Family = Daughter - Wife + Father + Mother
Therefore :: Family = - Daughter + Wife - Father - Mother
[ A Family only exists if there is a wife to have *x* with the husband ]
I only show 1 answer
There are all together 4 answers
Subtitute in and let " Family = "
