One-Step Equation Solver
How It Works
This one-step equation solver uses established formulas to provide accurate results.
The basic rule:
- ax = b → x = b/a
- x + a = b → x = b - a
- x - a = b → x = b + a
Results are estimates. Consult a professional for critical decisions.
Frequently Asked Questions
What is a one-step equation?
A one-step equation requires only one operation to solve for the variable. Examples include x + 5 = 12, 3x = 15, or x/4 = 8. You perform one inverse operation to isolate the variable.
How do you solve a multiplication equation?
Divide both sides by the coefficient. For example, 5x = 30: divide both sides by 5 to get x = 6.
What is an inverse operation?
An inverse operation 'undoes' another operation. Addition and subtraction are inverses; multiplication and division are inverses. You use inverse operations to isolate the variable when solving equations.
How do you check your answer?
Substitute your answer back into the original equation. If both sides are equal, your answer is correct. For 5x = 30, check: 5(6) = 30 ✓
