Question

解方程1、2

Answer 1

1 4/3[1/2(x-1/4)-8]=(3/2)x·4/3

(1/2)x - 1/8 - 8 =(3/2)x

x=8又1/8

2 1/2{x-(1/3)[x-(1/4)x+(1/6)]-2/3}=x+(3/4)

1/2{x-(1/4)x-(1/18)-2/3}=x+(3/4)

(-5/4)x=20/9
x=-16/9

希望能帮到你！

第一题是对的，第二题书上结果和这个不一样，我把图片给你看看，我觉得书上答案也有问题，所以才问的

我画圈的你看一下。

Answer 2

解：
（1）：
3/4{4/3[1/2(x-1/4)-8]}=(3/2)x
4/3[1/2(x-1/4)-8]=(3/2)x·4/3
1/2(x-1/4)-8=(3/2)x·4/3·3/4
(1/2)x - 1/8 - 8 =(3/2)x
(3/2)x-(1/2)x=1/8 + 8
x=8又1/8
（2）1/2{x-(1/3)[x-(1/4)x+(1/6)]-2/3}=x+(3/4)
1/2{x-(1/3)[(3/4)x+(1/6)]-2/3}=x+(3/4)
1/2{x-(1/4)x-(1/18)-2/3}=x+(3/4)
(3/4)x-(1/18)-2/3=2x+(3/2)
(-5/4)x=20/9
x=-16/9
