66=X+0.25X求X9.66=X+0.25X1.25x=9.66解得x=7.728有什么不明白的可以继续追问,望采纳!9.66=x(1+1/4)9.66=x*5/49.66*4=5xx=9.66*0.8=7.7289.66=X+0.25

0.25x+3.6=x解x等一下子

0.25x(1)0.25X0.25x由0.25x1.25x＜150x＜120由150-x150＜1.5xx＞100综上，100＜x＜120由0.25x0.25x+xx又由150-x150x>100所以100分解成0.25x150-x分别解得

x-0.25=0.25xx-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=0.3333333x/4=1/4x=1/3x-0.25=0.25x0.75x=0.25x=1/30.75
