0.1X+90=0.09X-9+200
0.01X=101
X=10100
（X+X)+(X-X)+(X*X)+(X/X)=100
X+X-10+X+8=100
求x:x(10^x)=100
100×2x+10x+3x+216=100×3x+10×2x+x
100(X - 2) + 10X + 2X = 100*2X + 10X + X - 2 - 495
X+X+X+X+X+X+100X=1690 问：X等于多少
求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x =100
100(x+4)+10x+(x+2)=21[10x+(x+2)]
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
(x+x)+(x-x)+(xx)+(x/x)=100 求x的值?用方程解
x-2x+3x-4x+5x.+99x-100x=25求解
2x+3x+4x+5x+x+6x+7x=100
30%x+10%(100-x)=100*x的过程
10/150x-1=10/100x.求x
100/x+1/2=150/(x+10) x=?
11x+64-10x=100-9x
10x+x^2-100=0,求x
