1. What is a Linear Equation?

A linear equation is an algebraic equation of the form ax + b = 0, where a and b are constants, and x is the variable. It represents a straight line when graphed on a coordinate plane.

2. How Does the Calculator Work?

The calculator solves linear equations using the formula:

Where:

• \( a \) — Coefficient of x (must not be zero)
• \( b \) — Constant term
• \( x \) — Solution to the equation

Special Cases:

• If a = 0 and b = 0: Infinite solutions
• If a = 0 and b ≠ 0: No solution

3. Importance of Linear Equations

Details: Linear equations are fundamental in mathematics and have wide applications in physics, engineering, economics, and various scientific fields. They form the basis for more complex mathematical concepts.

4. Using the Calculator

Tips: Enter the coefficient (a) and constant (b) values. The coefficient cannot be zero for a unique solution. The calculator will handle special cases automatically.

5. Frequently Asked Questions (FAQ)

Q1: What if the coefficient a is zero?
A: If a = 0 and b = 0, there are infinite solutions. If a = 0 and b ≠ 0, there is no solution.

Q2: Can I use fractions or decimals?
A: Yes, the calculator accepts both decimal and fractional inputs (converted to decimals).

Q3: What is the range of values accepted?
A: The calculator accepts any real numbers for both a and b parameters.

Q4: How precise are the results?
A: Results are calculated with high precision and rounded to 4 decimal places for readability.

Q5: Can this solve systems of equations?
A: No, this calculator only solves single linear equations of the form ax + b = 0.
