A)
|x + 19| = 17
x + 19 = 17 ∨ x + 19 = -17
x = 17 - 19 ∨ x = -17 - 19
x = -2 ∨ x = -36
B)
|x - 19| = 17
x - 19 = 17 ∨ x - 19 = -17
x = 17 + 19 ∨ x = -17 + 19
x = 36 ∨ x = -2
C)
|x - 17| = 19
x - 17 = 19 ∨ x - 17 = -19
x = 19 + 17 ∨ x = -19 + 17
x = 36 ∨ x = -2
D)
|x + 17| = 19
x + 17 = 19 ∨ x + 17 = - 19
x = 19 - 17 ∨ x = -19 - 17
x = 2 ∨ x = -36
