快快快快快快快快！

Answer 1

12.6-1.8x+1.8=3.6
解：14.4-1.8x=3.6
1.8x=14.4-3.6
1.8x=10.8
x=6

Answer 2

12.6-1.8x+1.8=3.6
则：1.8x=12.6+1.8-3.6
1.8x=10.8
则：x=10.8/1.8=6

Answer 3

12.6-1.8x+1.8=3.6
14.4-1.8x=3.6
1.8x=14.4-3.6
1.8x=10.8
x=6

Answer 4

12.6-1.8x+1.8=3.6
12.6=3.6-1.8+1.8x
12.6=1.8+1.8x
10.8=1.8x
x=6

Answer 5

1.8x=10.8
x=6
