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.

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.
