1.(x-1.5-1)/4=(x-1.5+1)/5
5(x-2.5)=4(x-0.5)
x=-2+12.5
x=10.5
2.l+300=30v
300-l=10v
v=15m/s
l=150m
3.80x+80y=400
80y-80x=400
所以x=0y=5
4.[x-4*（18-x-y)/60]/4=（18-y）/60
y/4=（18-x）/60+（18-x-y）/60
所以x=2y=2
5.x=4y
3x+11-x-y=25
x=8
y=2
6.(x-2)12=8x
x=6
7.x+y=4/5.2
x-y=4/6.5
解得:x=9/13,y=1/13
8.5*(1/3)+5*X=15*X
x=1/6
9.(1/3)x/12=(1/3)x/[12*(5/4)]+1
化简得：
(5/3)x=(4/3)x+60
(1/3)x=60
x=180
10.2X+5X=14000
7X=14000
X=2000
2X=4000
5X=10000
11.x+(35-20)*1.5%x=1323x=1080
12.2x-10.3x=15

17.3x-7(x-1)=3-2(x+3)
18.18x+3x-3=18-2(2x-1)
19.3(20-y)=6y-4(y-11)
20.-(x/4-1)=5
