又係哦....
可能Sunhee真身係Sunhee.....
但係佢又係十狂兄嘅化身....
十狂兄嘅化身係Zeo....
Zeo嘅化身又可能係幻象...
幻象嘅化身又可能係松田....
松田嘅化身又可能係閙爆叔.....
咁我好亂架喎~
等我用小四代入法扇一扇佢先.
十狂+Zeo =閙爆叔
幻象+Sunhee= 十狂
代入法:
從(1)十狂,
3m+7n = -90 Zeo←全式乘10
m = (-7n﹣90)/3 -(3)
從(2)Zeo,
m + 2n = -36 -(4)十狂←全式乘4
將(3)松田代入(4),
(-7n﹣90)/3 + 2n = -36
-7n﹣90 + 6n = -108
18 = n
n = 18 -(5)
將(5)幻象代入(3),
m = [-7(18)﹣90]/3
m = -72
∴m = -72 ,n = 18
消元法:
從(1)十狂,
3m+7n = -90 -(3)松田←全式乘10
從(2),
m + 2n = -36 -(4)幻象←全式乘4
(4)×3:3m+6n = -108 -(5)
(3)﹣(5):n = 18 -(6)
將(5)代入(4),
m + 2(18) = -36
m +36 = -36
m = -72
∴m = -72 ,n = 18
