20000(1+40%)=20000-x+(4x+2000)怎么算?20000(1+40%)=20000-x+(4x+2000)怎么算?20000(1+40%)=20000-x+(4x+2000)怎么
20000(1+40%)=20000-x+(4x+2000) 怎么算?
20000(1+40%)=20000-x+(4x+2000) 怎么算?
20000(1+40%)=20000-x+(4x+2000) 怎么算?
20000(1+40%)=20000-x+(4x+2000)
20000*1.4=20000-x+4x+2000
3x=22000-28000
3x=-6000
x=-2000
20000+20000*40%=40000+3x
8000=20000+3x
3x=-12000
x=-4000
20000-x+(4x+2000)=20000(1+40%)
x=2000
20000(1+40%)=20000-x+(4x+2000)
解方程x(1+2.88%)^6-x=1/2 10(20000-x) 6.21%-(20000-x)
x-(1/2x+20000)-{3/4[x-(1/2x+20000)]-10000}=205000 x=?
20000(1+40%)=20000-x+(4x+2000) 怎么算?
解方程 x-1%x=19.8x-40%x=15x+25%x=2.550%x+x=31.5x-15%x=8.5
56000/2x - 20000/x =20
X(X-1)=X
解分式方程:1/X-2+1/X-6=1/X-7+1/X-11/X-2+1/X-6=1/X-7+1/X-11/(x-2)-1/(x-1)=1/(x-7)-1/(x-6)(x-1-x+2)/(x-2)(x-1)=(x-6-x+7)/(x-7)(x-6)1/(x-2)(x-1)=1/(x-7)(x-6)(x-2)(x-1)=(x-7)(x-6)x^2-3x+2=x^2-13x+4213x-3x=42-210x=40x=4 为什么要移向才能解
(x+40)/60-x/40=1+0.5,x=?
(1-x)(400+40x)=300x=?
x*(1+40/100)*0.8-x=15 X=?
x/40+x/50=1+1/200*x
解几个1元2次方程[1500*(1+X)-435]*(1+X)=130810000(1+6%)(1+6%)20000(1+6.2%)100(1+X)+[100(1+X)](1+10%+X)=56(X-21)(350-10X)=400
解方程:x-40%x+12=x-1/4
x-1/5x-40%x=20 怎么解
解方程;x-1/3x-40%x=100
X-40%X-1/3X=15求算式
X-40%X-1/3X=15
