(解方程)73/100×3-3x=0.(解方程)73/100×3-3x=0.(解方程)73/100×3-3x=0.73/100×3-3x=0.0673/100×3-3x=6/10073x3/100-6

(解方程)73/100×3-3x=0.
(解方程)73/100×3-3x=0.

(解方程)73/100×3-3x=0.
73/100×3-3x=0.06
73/100×3-3x=6/100
73x3/100-6/100=3x
3x=219/100-6/100=(219-6)/100
=213/100
两边同除以3得:x=71/100
所以:x=71/100=0.71

分数加上括号才看得清楚!如果你是说(73/100)×3-3x=0.06的话:73×3-300x=6;213=300x;x=71/100
