x-35%x=0.25x-35%x=0.25x-35%x=0.25x-35%x=0.250.65x=0.25x=0.25÷0.65X=5/13x(1-o.35)=0.25x=0.25/0.35x=5/
x-35%x=0.25
x-35%x=0.25
x-35%x=0.25
x-35%x=0.25
0.65x=0.25
x=0.25÷0.65
X=5/13
x(1-o.35) =0.25
x=0.25/0.35
x=5/7
x-0.35x=0.65x=0.25，解得x=5/13
35%化为小数0.35 x-0.35x=0.25
0.65x=0.25
x=0.25÷0.65=5/13约等于0.3846
x-35%x=0.25
(x+35)-(x+20)=(x+20)*0.25 现在就要
（X+X)+(X-X)+(X*X)+(X/X)=100
（x-4)-(x+4)=0.25x
66=X+0.25X求X
0.25x+3.6=x解x
x+35=(x+3x)*30%
当X=7.5/35,4 X+6X-0.25X 等于多少
x-0.25x+1=10.4x+0.25x-1
x-0.25=0.25x
{x+10}x{x+10}=0.25x
X-35%X=7.8 X+160%X=39
如果X+X+8=35-X,那么X=( )
x-0.25x=0.
X-0.25x=0.
x-0.25x=48
x-1.75x=0.25
x-0.25x=15
