x-0.25=0.25x
x-0.25=0.25x

x-0.25=0.25x
x-0.25=0.25x
化为x-0.25x=0.25即0.75x.=0.25所以x=0.25/0.75=1/3=0.333333

3x/4=1/4
x=1/3

x-0.25=0.25x
0.75x=0.25
x=1/3

0.75X=0.25,X=0.3333333

x=0.5

x-0.25x=0.25
0.75x=0.25
x=1/3

（x-4)-(x+4)=0.25x 66=X+0.25X求X 0.25x+3.6=x解x x-0.25=0.25x x-0.25x+1=10.4x+0.25x-1 x-0.25x=0. X-0.25x=0. x-0.25x=48 x-35%x=0.25 x-1.75x=0.25 x-0.25x=15 X-0.25x=0. x-0.25x=2.4 (x-3.6)/x=0.25 x-12=0.25x 12.5-0.25X=X x-0.25x =5.7 x-0.25x=7.5
