$2(4c-7)=8c+14$
$8c-14 = 8c +14$

Slight mistake in the next part..
Go slow and steady and do the same on both sides..
Do ONE step at a time..

Actually this one doesn't make any sense.
Are you sure it's correct ?

Well actually this is how it works out.

8c-14=8c+14
8c-14-8c=14
so
0c-14=14
0c-14+14=14+14
0c=28 !!

See the problem here...

Because then you get
0c-28=0
so
0c=28
as I posted above.

Now what happens when you divide anything by ZERO ?
