5. Solving Equations Involving Absolute Value

Continue to next subchapter

Exercise 34 Page 106

Absolute values can be interpreted as the distance from a center point.

$∣ x ∣ = 6$

Practice makes perfect

Absolute values can be interpreted as the distance away from a midpoint. For one-variable absolute value equations, this distance can be represented by two points on a number line, such as the ones given in the exercise.

Because our equation needs a

distance

from a

midpoint,

we should begin by finding the halfway point between the two given values. We can do this by calculating their mean.
