(1560-X)/X*100%=25%怎么解?(1560-X)/X*100%=25%怎么解?(1560-X)/X*100%=25%怎么解?(1560-X)/X*100%=25%25%x=1560-x1
(1560-X)/X*100%=25%怎么解?
(1560-X)/X*100%=25%怎么解?
(1560-X)/X*100%=25%怎么解?
(1560-X)/X*100%=25%
25%x=1560-x
1.25x=1560
x=1248
(X+X)+(X-X)+(X*X)+(X/X)=100
x-2x+3x-4x+5x.+99x-100x=25求解
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+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
(1560-X)/X*100%=25%怎么解?
(100-x)/x=25% 求x怎么算?
600-25X+100X-5X^2=840
125+x-25=100 x=?
100^1/x=25求x,
(25+x)/(100+x)=40%
解25x=100+5x
x+25%*x=100 怎么解
(100-X)/X=25% 解是多少
150-x/x*100%=25%
8(x+15)-20=10x 2(100-x)-15=150-x 25x-165=10(15-x) 5(x-10)=3x-6
