x+½x+½x=2x
(98-X)+(100-X)+X=X/0.
解方程:100x+10(x+1)+(17-x-x-1)=100(17-x-x-1)+10(x+1)+x+198 x=?回答将被采解方程:100x+10(x+1)+(17-x-x-1)=100(17-x-x-1)+10(x+1)+x+198 x=?回答将被采纳为满意回答,)
100+x=200
100+x=10
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
4X+(100-X)/4=100
计算1/x(x+2)+1/(x+2)(x+4)+…+1/(x+98)(x+100)
x/60+2x/100=2.2
5X+10*(14-X)=100
10x+5=(5×100+x)+108
100+(X-100)/10=200+[X-200-100-(X-100)/10]/10
已知x^4+x^3+x^3+x^2+x^1+1=0,求x^100+x^99+x^98+x^97+x^96的值
请问(x+x)×x÷x﹣x=25 x=?(x等于同一数)
(X+X)+(X-X)+(X*X)+(X/X)=100
x+2/x+1=5/x-1/x(x+1) 求化简!
