(x-160)*67%/8400=(x-320)*67%/8000
两边同时除于67%
(x-160)/8400=(x-320)/8000
两边再同时乘400
对角相乘得
20(x-160)=21(x-320)
20x-21x=20*160-21*320
x=6720-3200
x=3520

(x-160)*67%/8400=(x-320)*67%/8000
(x-160)/8400=(x-320)/8000
(x-160)/84=(x-320)/80
20(x-160)=21(x-320)
20x-21x=20*160-21*320
x=3520

(x-160)*67%/8400=(x-320)*67%/8000
两边同时除于67%
(x-160)/8400=(x-320)/8000
两边再同时乘于100
(x-160)/84=(x-320)/80
再乘于1680
20(x-160)=21(x-320)
20x-21x=20*160-21*320
x=6720-3200
x=3520
