(500-x)*1.5-13.5x=705怎么解(过程)
(500-x)*1.5-13.5x=705怎么解(过程)
(500-x)*1.5-13.5x=705怎么解(过程)
(500-x)*1.5-13.5x=705
750-1.5x-13.5x=705
15x=45
x=3
x+(x+20)+(x-10)+70+x=540 .
0.3+0.3x=0.39 x= 2x-1.5x=7.6x x= 0.36x÷0.3=1.2 x=6(x+1.2)=18.6 x= 7x+2x = 8.1 x= (x-5)÷3=1.7 x=5(x+1.1)=15.5 x= 9x+25=70 x= 7x-4x=2.1 x=
(x+x)+(x-x)+(x/x)=11.2
x+ x+(x*50%)=1.5X?
X/1.5-60=X/13.5+60 X=?
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
1.5X+3.5X=13.5
(30+x)/(70+x)=3 x=
(25-30)*1.5%x+x=1323 x=?
1.5x+1.2x(210-x)=300
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
40(x+60)=70x
4x-(25-x)=70
(1.5x+x)×2=120
2(x-7.5)=1.5x
2(X-1.5)=X+2.7
1.5x(x-3)=60
7.3-x=0.6(x+1.5)
