Solve a Distance Equation in Both Directions
Absolute value measures nonnegative distance from zero.

Open lesson 1Algebra1: Solution Sets and Parameters
An equation may describe distance, a bounded interval, a parameter-dependent relation or a formula between several quantities. Its solution must respect all stated conditions, including endpoint inclusion and nonzero divisors.
Before you begin
- Solve two-step equations; order real numbers; distinguish a variable from a given constant.
Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.
