25%x+(1-25%)*20%x+6=x
25%x+(1-25%)*20%x+6=x
x-30%x=14x+25%x=20
{20%x+25}/{x-20%x-25}=5/6
(1/6x+25):x=1:
x/2+x/6+x/12+x/20+x/30+x/42=1
x-78%x=8.8 (1+25%)x=46 25%x/2=5 x+30%x=52 6%x-0.8%x=10.4 7.3
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
x+(20%+x)+(1+20%)x+(1+20%)x.25=3700 怎么算啊
6x+150%x=9 18-20%x=8 x-25%=0.8
1】20-25%x=15.5x 【2】4x+2(8-x )=26
这些解方程:x-6=15%x12 x-10%x=18 40%x+1/5x=15 25%x-5=60%x 5 3x+20%
x*x+2x+x*x+10x+x*x+25+2x+x*x+1+1+16+x*x+4x*x+9-12x+16x*x+4-1
