0.8x＋189－0.9x＝130
0.1x＝59
x＝590
x×1.4×0.8+(210-x)×1.4×0.9=182
1.12x+(210-x)×1.26=182
1.12x+264.6-1.26x=182
-0.14x=-82.6
x=590
展开式子:-10％x=182-210*140％*90％
-0.1x=-84.6
x=846
x＋60%x＝80 80%－30x＝305 35%x＝210 x＋50%x＝60 x－40%x＝0x＋60%x＝8080%－30x＝30535%x＝210x＋50%x＝60x－40%x＝0.36（1－80%）x＝21么么哒!
x+(x-140)+(x-210)=270 x=?
