解方程和简便计算解方程：1.5（x+4）-2x=x+482.4.5-x=2x-63.0.3x+7x-0.25x=21.15能简便的要简便`不简便的要按顺序计算`（乘先减后的那些都会吧`）1.（根据我的眼光`这道是简便的）4.68×1.1-0.468+4.68×92.（再根据我的眼光`这道是不简便的）[（8.73-8.23）×0.6-0.1]÷0.053.（还根据我的眼光`这道是简便的`）0.5×[9.9-（10-0.56÷5.6）]4.（我不根据了`自己看着办吧`）0.01÷[（3.8+4.02）÷78.2]-0.01

与上同样：
1. 4.68×1.1-0.468+4.68×9
=4.68×1.1-(0.468×10)+4.68×(9÷10)
=4.68×1.1-4.68+4.68×0.9
=4.68×1.1+4.68×0.9-4.68
=4.68×(1.1+0.9-1)
=4.68×1
=4.68
2. [(8.73-8.23)×0.6-0.1}÷0.05
=[0.5×0.6-0.1]÷0.05
=[0.3-0.1]÷0.05
=0.2÷0.05
=4
1. 4.68×1.1-0.468+4.68×9
=4.68×1.1-(0.468×10)+4.68×(9÷10)
=4.68×1.1-4.68+4.68×0.9
=4.68×1.1+4.68×0.9-4.68
=4.68×(1.1+0.9-1)
=4.68×1
=4.68
2. [(8.73-8.23)×0.6-0.1}÷0.05
=[0.5×0.6-0.1]÷0.05
=[0.3-0.1]÷0.05
=0.2÷0.05
=4
我不是抄的

1. 4.68×1.1-0.468+4.68×9
=4.68×1.1-(0.468×10)+4.68×(9÷10)
=4.68×1.1-4.68+4.68×0.9
=4.68×1.1+4.68×0.9-4.68
=4.68×(1.1+0.9-1)
=4.68×1
=4.68
2. [(8.73-8.23)×0.6-0.1}÷0.05
=[0.5×0.6-0.1]÷0.05
=[0.3-0.1]÷0.05
=0.2÷0.05
=4
别泄气

我来算递等计算吧,
1.4.68×1.1-0.468+4.68×9
=4.68×1.1-(0.468×10)+4.68×(9÷10)
=4.68×1.1-4.68+4.68×0.9
=4.68×1.1+4.68×0.9-4.68
=4.68×(1.1+0.9-1)
=4.68×1
=4.68
2.[(8.73-8.23)×0.6-0.1}÷0.05
=[0.5×0.6-0.1]÷0.05
=[0.3-0.1]÷0.05
=0.2÷0.05
=4
