6x+0.7=12.96x+0.7=12.96x+0.7=12.93.6x+0.7=12.93.6x=12.2x=61/18=3.388893.6x=12.2x=18/61x=(12.9-0.7)/3
6x+0.7=12.9
6x+0.7=12.9
6x+0.7=12.9
3.6x+0.7=12.9
3.6x=12.2
x=61/18=3.38889
3.6x=12.2
x=18/61
x=(12.9-0.7)/3.6=3.39
通过移项,原式得:3.6X=12.9-0.7=12.2,所以等式两边同时除以3.6即12.2除以3.6解得X=十八分之六十一,用小数表示就是3.38888888888.。。。。。八的无限循环,约等于3.4.
3.6x=12.2
x=61/18
3.6x=12.2
x=61/18=3.38889
