No. I'd give you the correct answer, but this is a very transparent attempt to get others to do your homework. And from the looks of it, you really need the practice, because this isn't a hard one.

3(4c+7) = 12c
12c + 21 = 12c
12c - 12c = -21
0 = -21
Oops!! This equation is flawed

3(4c+7)=12c
12c+21=12c
21=12c-12c
21=0

I am sorry, did you think to stay in Math's Zone?
This is Chemistry's Area!
GRAPHIC APPROACH
Nonetheless, did you sketch this trouble in a "Y vs. X" 's chart?
You draw two STRAIGHT LINES, e.g.
Y1 = 3 * (4 * X1 + 7) = 12 * X1 + 21
Y2 = 12 * X2
which are result as ALIGNED LINES.
A Greek mathematician, Euclide, defined this concept as LINES able to cross one to the other only at the
"Y vs. X"-Space's BOUNDARies.
Did you understood?
MATH APPROACH
I rearrange the terms in the following fashion
3 * (4 * c +7) = 12 * c
12 * c + 21 = 12 * c
12 * (c / c) + (21 / c) = 12
permitted only when I refused c = 0
12 + (21 / c) = 12
(21 / c) = 12 - 12 = 0
which is leading me to think "c" as the Greatest among the Number.
I hope this helps you.
