WA+AB=1 ==> WA=1-WB
±N¦¹ ¥N¤J ²Ä¤G¦¡

WA*2.8954 + WB*0.7864 = 5
(1-WB)*2.8954 +0.7864WB = 5
2.8954 - 2.8954WB + 0.7864WB = 5
-2.8954WB+ 0.7864WB = 5 - 2.8954
-2.109WB = 2.1046
WB= 2.1046 / -2.109
WB=-0.997913703
WA=1-WB= 1- (-0.997913703)= 1.997913703

Åçºâ
1.997913703 * 2.8954 + 0.7864(-0.997913703 )
= 5.765813567 - 0.779613603 = 5.???

Ans¡G

WA+WB=1
2.8954*WA+2.8954*WB=2.8954-------1¦¡
WA*2.8954+WB*0.7864=5-------2¦¡
2¦¡-1¦¡=-2.109*WB=4
WB=-4000/2109
WA=1-WB
1-(-4000/2109)=2109/2109+4000/2109=6109/2109

WB=-4000/2109
WA=6109/2109 #
