2x+4\uff0820-x\uff09=46
2x+80-4x= 46
2x=34
x=17
X/80=X/120+20
80（X+2400)=120X
X=4800 2.16÷4=4
100-4=96
96÷(2+1)=32
32+4=36
100-36=64
鸡64,兔36 3. 解：设步行x分钟，则骑自行车10-x分
210*(10-x)-80*x=215
2100-210x-80x=215
290x=1885
x=6.5
10-x=3.5
答：步行6.5分钟，行自行车3.5分钟
1 ，设大筐可以装X千克，小筐可以装（X-20）千克，80*X=120*(X-20) ， 求出X=60，则水果有60*80=4800千克。
2，设鸡有X只，则兔有（100-X）只，2*X=4*(100-X)-16，算出鸡有64只，则兔子有36只。
3，设走路为X米，则骑车为（X+215）米，X/80+（X+215)/210=10，算出X=520米，则走里520/80=6.5分钟，骑车（520+215）/210=3.5分钟。
1.4800千克
2.64只鸡，36只兔
3.6.5分钟走路，3.5分钟骑车
2. 鸡比兔少16除以2=8 100-8=92 兔有92除以2=46只 鸡有100-46=54只
对不起，我只知道这一题
