How to Solve a Linear Equation
A linear equation is an equation in which the variable has a power of one. The goal is to isolate the variable on one side while keeping the equation balanced.
Example: Solve 2x + 5 = 15
Step 1: Start with 2x + 5 = 15.
Step 2: Subtract 5 from both sides: 2x = 10.
Step 3: Divide both sides by 2: x = 5.
Check: Substitute x = 5 into the original equation. Since 2(5) + 5 = 15, the answer is correct.
Types of Equations Supported
- One-step equations, such as x + 4 = 10.
- Two-step equations, such as 2x + 5 = 15.
- Variables on both sides, such as 3x – 7 = 2x + 8.
- Simple decimal equations, such as 1.5x = 6.
- Simple fractional coefficients, such as x/2 + 3 = 7.
Quadratic equations, parentheses, powers, and systems of equations require a more advanced solver and are not supported here yet.
Frequently Asked Questions
What is a math equation solver?
A math equation solver is a tool that calculates the unknown value in an equation and can explain the steps used to find it.
Is this math equation solver free?
Yes. This version runs in your browser without a paid AI API or a subscription to an equation-solving service.
Can it solve equations with x on both sides?
Yes. It supports linear equations with x terms on both sides, such as 3x – 7 = 2x + 8.
Can it solve quadratic equations?
No. This initial version supports linear equations in one variable. Quadratic equation support can be added separately.
Does the solver show steps?
Yes. It displays the simplified equation, variable isolation, division where needed, and a final-answer check reminder.
