x - 2 = 9 What is one possible solution to the given equation?

Question

Accepted Answer

The correct answer is 11 or - 7 . By the definition of absolute value, if x - 2 = 9 , then x - 2 = 9 or x - 2 = - 9 . Adding 2 to both sides of the equation x - 2 = 9 yields x = 11 . Adding 2 to both sides of the equation x - 2 = - 9 yields x = - 7 . Thus, the given equation, x - 2 = 9 , has two possible solutions, 11 and - 7 . Note that 11 and -7 are examples of ways to enter a correct answer.
