How do you solve the equation #20=-4c-8#?

Answer 1

Abigail Allen

#c=-7#

I would take the #-4c# over the other side of the equals sign and make it positive to give:

#4c+20=-8#

After that, you can take 20 off of each side to get;

#4c=-20-8#

#4c=-28#

To get: divide both sides by four.

#c=-7#

To solve the equation 20 = -4c - 8, you first add 8 to both sides to isolate the term with the variable. This gives you 20 + 8 = -4c. Simplifying, you have 28 = -4c. Then, divide both sides by -4 to solve for c. This yields c = -7.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
