这个方程怎麼解（请打出解的过程）

（1-1/5）X=44-X+2.8
解： 4/5X=44-X+2.8
X+4/5X=44+2.8
9/5X=46.8
X=46.8*5/9
X=5.2*5
X=26

（1-1/5）X=44-X+2.8
4/5X=46.8-X
4/5X+X＝46.8
1.8X＝46.8
X＝26

原式化成 0.8X=44-X+2.8
0.8X+X=44+2.8
1.8X=46.8
得出X=26

0.8x=44-x+2.8
0.8x+x=44+2.8
1.8x=46.8
x=26

x=44-x+2.8
解:x+x=44+2.8
2x=46.8
x=23.4

4/5X=46.8-X
(4/5+1)X=46.8
9/5X=46.8
X=46.8*5/9
X=26
