780-x=0.25x
780=1.25x
x=624
(675-y)/y*100%=10%
675-y=0.1y
675=1.1y
y=675/1.1
(X+X)+(X-X)+(X*X)+(X/X)=100
x-2x+3x-4x+5x.+99x-100x=25求解
(100-x)/x=25% 求x怎么算?
解方程:x-2x+3x-4x+...+99x-100x=25
解方程:x-2x+3x-4x+.+99x-100x=25
x-2x+3x-4x+...+99x-100x=25

x^2+x^-2=x^4,化简(x+x^-1+x2)(x-x^-1+x²)(-x+x^-1+x²)(x+x^-1-x²)第18题,
X+X+X+X+X+X+100X=1690 问:X等于多少
100X的平方+10(X+3)+X=202+25(X+3) 求X
(X-17)+(X-21)+(X-25)+.+(X-57)=33,求X=?
(x+1)X百分之三十+(100-X)X百分之二十五=2/5X
