Question

–3(c + 14) + 3 = 15 solve for c

Answer 1

c = -18

Explanation:

We need to distribute the -3 to each term within the parentheses. This essentially means finding the sum of the product of -3 with each of those inner terms:

-3 * c + (-3) * 14 + 3 = 15

-3c - 42 + 3 = 15

-3c = 15 + 42 - 3 = 54

c = 54/(-3) = -18

c = -18

Answer 2

c = -18

Explanation:

–3(c + 14) + 3 = 15

⇔

–3c - 42 + 3 = 15

⇔

-3c = 15 + 42 - 3

⇔

-3c = 54

⇔

c = - 54/3

⇔

c = -18
