13-0.2(x+2)=13-2.4怎么解,13-0.2(x+2)=13-2.4怎么解,13-0.2(x+2)=13-2.4怎么解,13-0.2(x+2)=13-2.413-0.2x-0.2*2=10

13-0.2(x+2)=13-2.4 怎么解,
13-0.2(x+2)=13-2.4 怎么解,

13-0.2(x+2)=13-2.4 怎么解,
13-0.2(x+2)=13-2.4
13-0.2x-0.2*2=10.6
移项
0.2x=13-0.4-10.6
0.2x=2
x=2÷0.2
x=10

13-0.2(x+2)=13-2.4
-0.2(x+2)=-2.4
x+2=12
x=10

原式等于
13-0.2x-0.4=13-2.4
-0.2x=-2
x=10

0.2(x+2)=2.4,所以x=1
