Two-Step Equation Solver
Enter any equation of the form ax + b = c and get the full unwrapping, step by step, with a substitution check at the end. For x/4 + 2 = 9, enter a = 1/4.
Solve ax + b = c
Enter integers, decimals, or fractions (like 1/4 or -2/3). The solver unwraps in reverse order and checks the answer.
