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

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

r and t.

both are 64 degrees.
