解方程 急急急急急

`````２分之1（３w－４）＋２＝４w－５（４分之w＋２）
4x[２分之1（３w－４）＋２]=4[４w－５（４分之w＋２）]
```````````````2x（３w－４）+8=16w-20（４分之w＋２)
``````````````````````````````6w-8+8=16w-5w-40
``````````````````````````6w-6w+40=16w-5w-6w+40
``````````````````````````````````````40=5w
```````````````````````````````````40/5=5w/5
```````````````````````````````````````w=8
唔洗理D點!
hope can help you!

1/2(3w-4)+2=4w-5(w/4+2)
3w-4=8w-10w/4-24
5w=10w/4+20
20w=10w+80
10w=80
w=8

1/2(3w-4)+2=4w-5(w/4+2)
3w-4=8w-10w/4-24
5w=10w/4+20
20w=10w+80
10w=80
w=8

(3W-4)/2+2=4W-5(w/4+2)

全條式x4

6w-8+8=16w-20(w/4+2)
6w=16w-5w-40
16w-5w-6w=40
5w=40
w=8

do u mean .5(3w-4) + 2 = (4w-5)? if so, w is 2. I dont get what you mean by "（４分之w＝＋２）"
