Free Algebra Solver with Step-by-Step Explanations

New: Check my work

Find the exact line where your math went wrong

I built this solver around the way I've taught math for more than 20 years: understanding comes first, answers come second. That approach shapes its two main features.

1

Step-by-step solutions modeled on my teaching

The solutions are designed to follow the way I explain problems in class: clear steps, with the calculations shown, so you can see where the numbers come from.

2

Check my work finds your mistake

Most solvers only give you the answer. Check my work looks at your solution. Type the steps you wrote, and it points to the first line that's wrong, much like a teacher checking your paper. You fix the mistake yourself, so you learn from it.

If your goal is to truly learn math, not just get answers, this solver is for you.

Example
Solve: 3(x − 2) = 12
13x − 6 = 12✓ correct
23x = 6✗ check this line
3x = 2
Why is line 2 wrong?To undo − 6, add 6 to both sides: 12 + 6 = 18, so 3x = 18.
  1. Solve the problem your wayon paper, like in class.
  2. Type your stepsone line at a time.
  3. See which line is wrongand correct it yourself.

Seeing which line is wrong is free. Members also get the explanation of the mistake, the corrected line, a link to the lesson on that skill, and a training mode that teaches how to write clear steps.

Stuck on a problem? See every step.

Our free Algebra Solver does more than give you the answer. It shows you exactly how to get there, one clear step at a time. Every number in a solution comes with the calculation behind it, so nothing is left to guesswork.

Many online solvers skip steps or hide the full explanation behind a paywall. This solver was built on a simple belief: students learn math by understanding where everything comes from.

  • Every step is explainedWhen the solver distributes, combines like terms or moves a number to the other side, it shows the arithmetic, such as 5 − 2 = 3 or (−6 − 4)y = −10y.
  • It checks its own answersEach solution ends by putting the answer back into the original problem to prove it works.
  • It connects to lessonsEach step links to the matching lesson on basic-mathematics.com, so you can review a skill the moment you need it.
  • It shows, not just tellsInequalities come with a number line, and equations of lines come with a graph.
  • It's freeNo account, no sign-up and no fee to see the algebra steps. It works on phones, tablets and computers.
  • It's easy to useA built-in keypad helps you type exponents, square roots and absolute value bars.

How to use it wisely

Try the problem on your own first. Then use Check my work to find any line that went wrong, and the step-by-step solution to compare your method with ours. Over time, you'll make fewer mistakes and gain real confidence.

The Algebra Solver is like having a patient tutor available any time, ready to walk you through each problem until it makes sense.
