How to Use the Math Solver

1. Choose Your Solver

Select the type of problem you want to solve using the tabs: a single-variable 'Equation', an 'Inequality', or a 'System of Equations'.

2. Enter Your Problem

Type your mathematical expression into the input field. For systems, enter one equation in each box. You can use `*` for multiplication and `^` for exponents.

3. Get the Solution

Click 'Solve' to see a detailed, step-by-step breakdown of the solution, the final answer, and an interactive graph visualizing the result.

Supported Formats

Equations/Inequalities: Use 'x' as the variable (e.g., `x^2 - 4 = 0` or `3x + 2 > 5`).
Systems: Use 'x' and 'y' as variables (e.g., `2x + y = 5` and `x - y = 1`).

How to Solve Linear Inequalities Step by Step

To solve a linear inequality like 2x + 3 < 7, subtract 3 from both sides, then divide by 2. Remember to reverse the inequality if you divide by a negative. Example: 2x + 3 < 7 → 2x < 4 → x < 2. Use our inequality solver above for instant solutions and number line graphs.

How to Solve Quadratic Equations with Steps

Quadratic equations have the form ax² + bx + c = 0. Use the quadratic formula: x = [-b ± √(b²-4ac)]/(2a). Enter your equation in the calculator above to see each step and the final answer, including decimal approximations.

How to Solve Systems of Equations by Substitution and Elimination

For systems like 2x + y = 5 and x - y = 1, use substitution (solve one equation for y, substitute in the other) or elimination (add/subtract equations to eliminate a variable). Our system solver shows the solution for x and y instantly.

How to Graph Solutions to Equations and Inequalities

Visualizing solutions helps you understand math problems. Our tool graphs equations and shows number lines for inequalities, so you can see roots, intersections, and solution intervals at a glance.
