Math Equation Solver Guide

How to Use the Math Equation Solver

1. Basic Equation Solver

  • Solves linear equations with one variable (e.g., x).

  • Format: Enter equations like 3x + 5 = 20 or 2(x - 4) = 10.

  • Examples:

    • 5x - 7 = 18 → Solves for x.

    • x/2 + 3 = 9 → Handles division.

    • 4(2x + 1) = 36 → Supports parentheses.

2. Quadratic Equation Solver

  • Solves equations of the form ax² + bx + c = 0.

  • Steps:

    1. Enter coefficients ab, and c.

    2. Click “Solve Quadratic.”

  • Examples:

    • x² - 5x + 6 = 0 → Enter a=1b=-5c=6.

    • 2x² + 4x - 6 = 0 → Enter a=2b=4c=-6.

  • Output: Real roots, complex roots, or double roots.

3. System of Equations Solver

  • Solves two linear equations with two variables (x and y).

  • Format: Enter both equations separately.

  • Examples:

    • 2x + 3y = 7 and x - y = 1 → Solves for x and y.

    • y = 2x + 1 and y = -x + 4 → Rewrite as 2x - y = -1 and x + y = 4.

  • Note: Equations must be in standard form (Ax + By = C).


Tips for Best Results

  • Use * for multiplication (e.g., 2*x instead of 2x if unsure).

  • For fractions, use parentheses (e.g., (x+1)/3 = 2).

  • Avoid spaces between numbers and variables (e.g., 3x, not 3 x).


Need Help?

  • Check the example formats above.

  • Ensure your equations are balanced (both sides of = are valid).
