解方程：(要有过程，不用写解)
8.5-x=3.7
0.81-x=0.51
8.6÷x=40
6.43-x=3.8

Answer 1

8.5-x+8.5=3.7+8.5
0.81-x+0.81=0.51+0.81
8.6÷x×8.6=40×8.6
6.43-x+6.43=3.8+6.43

Answer 2

1.X=8.5-3.7，X=4.8
2.X=0.81-0.51，X=0.3
3.X=8.6/40,X=43/200
4.X=6.43-3.8,X=2.63

Answer 3

1.x=3.7+8.5 X=12.2 2.x=0.51+0.81 x=1.32 3.x=40x8.6 x=384 4.x=3.8+6.43 X=10.23

Answer 4

①x=8.5-3.7 x=4.8②

追答

x=0.81-0.51 x=0.3③x=8.6÷40 x=0.215

x=6.43-4.8x=1.63

Answer 5

1、8.5-3.7
