Question

Solve - ( c - 3) = 6

Answer 1

Distribute the negative outside the parenthesis through the terms inside the parenthesis.

-c + 3 = 6

Subtract 3 from both sides.

-c = 3

Divide both sides by -1.

c = -3

Answer 2

Greetings!

$-(c-3)=6$
Distribute the Parenthesis.
$-c+3=6$
Add -3 to both sides.
$(-c+3)+(-3)=(6)+(-3)$
$-c=3$
Divide both sides by -1.
$(-c)/-1=(3)/-1$
$c=-3$

Hope this helps.
