Question

这道题怎么算？

求助

Answer 1

解：1/4x+80+1800=x-(1/4x+80)

1/4x+1880=x-1/4x-80

x-1/4x-1/4x=1880+80

1/2x=1960

x=1960÷1/2
x=3920
所以原方程的解为X=3920

Answer 2

解:1/4x+80+1800=x-(1/4x+80)1/4x+1880=x-1/4x-80
1880+80=x-1/4x-1/4x
1/2x=1960
x=1960x2
x=3920

Answer 3

解:
1/4x+80+1800=x-(1/4x+80)
1/4x+1880=x-1/4x-80
1880+80=x-1/4x-1/4x
2/4x=1960
x=1960÷2/4
x=3920

Answer 4

解:
1/4x+80+1800=x-(1/4x+80)

1/4x+1880=x-1/4x-80

1880+80=x-1/4x-1/4x

2/4x=1960

x=1960÷2/4

x=3920

Answer 5

解:移项 1/2x＋80+80+1800=x
1/2x＝1960
x＝3920
