100*20%=(x+100)*10%怎么解(详细解答)?
100*20%=(x+100)*10%怎么解(详细解答)?
100*20%=(x+100)*10%怎么解(详细解答)?
100*20%=(x+100)*10%
100*0.2=0.1x+10
0.1x=10
x=100
这个直接带入公示啊
200=100+x
x=100
左边=20,右边=0.1x+10,左边=右边,得20=0.1x+10,即x=100.
(X+X)+(X-X)+(X*X)+(X/X)=100
(20-x)(100+10x)=2240
20*(100-x)-10x=1640
X+X-10+X+8=100
求x:x(10^x)=100
8(x+15)-20=10x 2(100-x)-15=150-x 25x-165=10(15-x) 5(x-10)=3x-6
8(x+15)-20=10x 2(100-x)-15=150-x 25x-165=10(15-x) 5(x-10)=3x-6
x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x4(x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-1
100×2x+10x+3x+216=100×3x+10×2x+x
100(X - 2) + 10X + 2X = 100*2X + 10X + X - 2 - 495
(100-2x-10x)/5=20-2x-2/5*x
30-3(3-X)=4X 3X+12*6=15X+12 4X-2(50-X)=20 12(X-13)=10(X+3) 100-X=3(20+X)
解方程:(1)2x-19=7x+31 (2)20-2x=x-1 (3)19-x=100-10x (4)1/3x+5=2/3x-62x-19=7x+317x-2x=-19-31这里应该是31+19吧?5x=-50x=-50÷5x=-10
解方程26(8-X)-6=150 4x-2(x+20)=40 4x-2(100-x)=40 4x-2(50-x)=20 9(x-8)=8x=10
100(x+4)+10x+(x+2)=21[10x+(x+2)]
求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x =100
一道一元一次方程,[100x+10(x-2)+24-x-(x-2)]-(10x+x)=100[24-x-(x-2)]+10(x-2)+x[100x+10(x-2)+24-x-(x-2)]-(10x+x)=100[24-x-(x-2)]+10(x-2)+x
100X的平方+10(X+3)+X=202+25(X+3) 求X
