10000/X*200=100*X-10000给出过程即可多少大虾们就不介意的吧,因为不难哦．～

（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 200x+170(70-x)+100(40-x)+x-10= 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 =100 400(20-X)(10-X)+200×【20x+(10-X)X】=55000怎么算! 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 请帮我解一个方程 写出每一步 2[100x+10(x+1)+2x]-49=200x+10(x+1)+x 19-200x+100x*x=0 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
