解方程(1)1/4x-1/12x=1/3 (2)x+1/2-x-1/3=1 (3)2x+1/3-(x-5)=2/3 (4)x+4/5-x+2/10=x-2/2

（1）1/4x-1/12x=1/3
x/6=1/3
x=2
(2)(x+1)/2-(x-1)/3=1
3(x+1)-2(x-1)=6
3x+3-2x+2=6
x=1
(3)2x+1/3-(x-5)=3/2
2(2x+1)-6(x-5)=9
4x+2-6x+30=9
-2x=-23
x=23/2
(4)x+4/5-x+2/10=x-2/2
2(x+4)-(x+2)=5(x-2)
2x+8-x-2=5x-10
x-5x=-10-6
-4x=-16
x=4
(5)2.4-x-4/2.5=3/5x
12-2(x-4)=3x
12-2x+8=3x
-2x-3x=-20
-5x=-20
x=4
(6) x-2/3-x-1/2=x+1
2(x-2)-3(x-1)=6(x+1)
2x-4-3x+3=6x+6
-x-6x=6+1
-7x=7
x=-1第4提错了吧= =应该是-4吧对不起，太大意了。
