Move all terms containing C to the left side of the equation. -8c-11=21

Move all terms not containing C to the right side of the equation. -8c=32

Divide each term by -8 and simplify.

32/8 equals -4

C=-4

<span> -4c - 11 = 4c +21 add 4c to both sides
</span>
<span> -4c - 11 + 4c = 4c + 21 + 4c simplify

- 11 = 8c + 21</span> <span> subtract 21 from both sides

- 11 - 21 = 8c + 21 - 21 </span><span>simplify

- 32 = 8c divide both sides by 8

c = - 4

That's it

I hope you got the idea
