x%0.52x=3.2×0.15(解方程)

0.48x=0.48 x=1

x-0.52x=3.2乘0.15 0.48x=0.48 x=1

x-0.52x=3.2×0.15 0.48x=3.2×0.15 x=3.2×0.15/0.48=0.2×15/3=1

x-0.52x=3.2×0.15 0.48x=0.48 x=1

x-0.52=1.3 x=1.3+0.52 x=1.82

原方程可化为 52x=234O, x=45。

X-35%X=0.52 x-0.35x=0.52 0.65x=0.52 x=52/65 x=4/5

(1)原方程去分母得:20x+50+4(5+2x)-3(4x+10)=0,去括号得:20x+50+20+8x-12x-30=0,合并同类项得:16x+40=0,化系数为1得:x=-52,故答案为-52.(2)原方程去括号得:116x-38-34-32-3=0,去分母得:x-6-12-24-48=0,移项,合并同类项得...

0.55*(1-x)+0.35*x=0.52 55*(1-x)+35*x=52 55-55x+35x=52 -20x=-3 x=3/20

0.4x+0.8x×15=52 0.4x+12x=52 12.4x=52 x=52÷12.4 x≈4.194
