100X+(100+100X)(X+10%)=56 怎么解

（X+X)+(X-X)+(X*X)+(X/X)=100 X+X-10+X+8=100 求x:x(10^x)=100 x+2x+3x+.+100x 100×2x+10x+3x+216=100×3x+10×2x+x 100(X - 2) + 10X + 2X = 100*2X + 10X + X - 2 - 495 X/100 + X/80 X+X+X+X+X+X+100X=1690 问：X等于多少 x(x-1)(x-2)...(x-99)(x-100) (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 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>7,x=100 x 3x=x+100 x=?
