Σ The Formula

x = (c - b) / a

Real World Examples

Simple Linear
2x + 4 = 10 → x = 3
Negative Coefficients
-3x + 9 = 0 → x = 3
Decimals
0.5x - 2.5 = 5 → x = 15

# About This Calculator

An algebra calculator is a utility designed to solve mathematical equations by isolating the unknown variable, typically denoted as $x$. This specific solver handles the most fundamental linear equation form: $ax + b = c$.

The process involves two primary steps: inverse operations. First, we use subtraction or addition to move the constant term ($b$) to the other side of the equation. Second, we use division or multiplication to move the coefficient ($a$) away from the variable.

Mastering this foundational "two-step" equation is the gateway to more complex algebra, including quadratic equations, systems of linear equations, and calculus.

How To Use

  1. Enter the coefficient **a** (the number in front of x).
  2. Enter the constant **b** (the number being added or subtracted).
  3. Enter the total **c** (the number on the right side).
  4. Click "Solve for x" to see the step-by-step solution.

Frequently Asked Questions

What if 'a' is zero?+

If 'a' is zero, the term containing x disappears, and the equation becomes a simple comparison (e.g., 4 = 10), which means there is no variable to solve for.

Can I use negative numbers?+

Yes! You can enter negative values for any of the fields. For example, '2x - 4 = 10' can be entered with b as -4.

Is Algebra Calculator free to use?+
