Algebra Solver Online — Free Step-by-Step Equations, Inequalities & Word Problems
Linear equations, quadratics, systems, polynomials, inequalities, word problems — type or photograph the algebra problem and get a full step-by-step solution.
How It Works
Enter or photograph the algebra problem
Type the equation in plain text or upload a photo. Standard math notation is supported.
ScanSolve picks the technique
Factoring, quadratic formula, substitution, elimination, completing the square — the AI identifies and applies the right method.
Read the solved problem
Each step is shown with the operation performed and the reasoning. Ask follow-up questions for unclear steps.
What Makes ScanSolve Different
Word problems, not just symbolic
ScanSolve reads the word problem, sets up the equation, solves it, and interprets the answer in context. Most algebra solvers stop at the equation.
Multiple methods on demand
Ask ScanSolve to solve a quadratic three different ways — factoring, quadratic formula, completing the square — and it shows each. Great for studying.
Inequality solutions explicit
Sign analysis, interval notation, number-line representation — ScanSolve walks through each.
System of equations: any size
Substitution and elimination for 2-variable systems, matrix methods (Gaussian, Cramer’s) for larger ones.
Practice generation
Ask for similar practice problems and ScanSolve generates them with worked solutions hidden until you’re ready.

Frequently Asked Questions
Does the algebra solver show all the steps?+
Yes. Every step shows the operation performed and the reasoning. You can also ask for an even more detailed breakdown of any specific step.
Can it solve word problems?+
Yes. ScanSolve reads the word problem, identifies the unknowns, sets up the equation(s), solves, and explains what the answer means in the original context.
What’s the difference between this and a graphing calculator?+
A graphing calculator gives you the answer. ScanSolve shows you HOW to get the answer, with each step explained — so you actually learn the method.
Is the algebra solver free?+
Yes. 5 free step-by-step solutions per day, no card required, no sign-up needed.
