Solve for all values of c in simplest form.
43=[c+21]

If those are absolute value lines: 22 and -64

Step-by-step explanation:

43 = | c + 21 | is an absolute value equation, meaning it has two answers.

To get the first you keep 43 positive and remove the absolute values and solve normally: 43 = c + 21 -> 43 - 21 = c -> c = 22.

To get the second you make 43 negative and remove the absolute values then solve: -43 = c + 21 -> -43 - 21 = c -> c = -64

43 = 22 + 21 -> 43 = 43

43 = -64 + 21 -> 43 = 43
