150-x=25x
26x=150
x=5.77
(X+X)+(X-X)+(X*X)+(X/X)=100
x-2x+3x-4x+5x.+99x-100x=25求解
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
8(x+15)-20=10x 2(100-x)-15=150-x 25x-165=10(15-x) 5(x-10)=3x-6
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
x的平方-25x-150=0 x=?
100/x+1/2=150/(x+10) x=?
10/150x-1=10/100x.求x
150/(x+0.5)-100/x=10求x
(100-x)/x=25% 求x怎么算?
600-25X+100X-5X^2=840
125+x-25=100 x=?
