Absolute Value Solver

Skill: absolute-value

Absolute Value Solver

Solve |ax + b| (comparison) c step by step — equations and inequalities — and see the solution set drawn on a number line.

1 Absolute Value Equation & Inequality Solver

Enter a, b, c and the comparison for |ax + b| (comparison) c. The solver isolates, splits into cases, and draws the solution set.

Input

Solution

Number line: the solution set is drawn in blue.

2 How it solves

The solver first checks the sign of c (a negative right side kills equations instantly), then solves −c < ax + b < c style bounds and flips the inequality if a is negative.
