解方程

6.72-1.2x=1.44

6.72-1.44=1.2x

1.2x=5.28

x=4.4

1.2x=6.72-1.44
1.2x=5.28

x=4.4

本题：6.72-1.2x=1.44

1.2x=5.28

x=5.28/1.2

x=4.4

6.72-1.2x=1.44

6.72-1.2x-6.72=1.44-6.72

-1.2x=-5.28

-1.2x/(-1.2)=-5.28/(-1.2)

x=4.4

解：

6.72-1.2x=1.44

6.72-1.2x+1.2x=1.44+1.2x

6.72=1.44+1.2x

6.72-1.44=1.44-1.44+1.2x

5.28=1.2x

5.28÷1.2=1.2x÷1.2

x=5.28÷1.2

x=4.4

回答完毕，顺祝学习进步！

1.2x=6.72-1.44=5.28

x=5.28÷1.2=4.4
