Absolute Value Equation Solver

Enter the coefficients a, b and c to solve |a·x + b| = c — with both solutions, the number of solutions, the two branch equations, and full step-by-step working.

Standard form:  |a·x + b| = c  ⟹  a·x + b = ±c
| a x + b | = c

Solving |a·x + b| = c. If c < 0 there is no solution; if c = 0 there is one; otherwise two. Decimals are fine.
