# 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
- Enter the coefficient **a** (the number in front of x).
- Enter the constant **b** (the number being added or subtracted).
- Enter the total **c** (the number on the right side).
- 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.
