- 3. Absolute Values Solving Equations Involving Absolute Values The absolute value can be thought of as its distance from 0 on a number line. Any positive and negative number are each a positive distance from 0. Absolute values are only concerned with distance rather than direction Ex. If the absolute value of m = 17, what are the possible values of m Ex. If x + 2 = 12 a) What are the possible values that x + 2 might equal? b) What are the possible values for x? Ex. 3

- 6. You must solve two equations One when the value of is equal to the positive value of the right side The other when the value of is equal to a negative value of the right side Once you find all of the possible values for x you must then check your solutions in the equation You will find through your check that some of the solutions may not be possible 6
