Welcome to Your Algebra Helper

Think of this calculator as your personal math tutor!


Whether you're working on homework, checking your answers, or just learning algebra, we're here to help you every step of the way.


Not only will we solve your problems, but we'll also show you exactly how we got there!

What Can This Calculator Do?

We can help you with two main things:


1. Solve Linear Equations:

Got an equation like '2x + 3 = 7'? We'll find the value of x for you!


2. Simplify Expressions:

Have something like '5x - 2x + 4 - 1'? We'll combine like terms and make it neat and tidy!

Learning Tips

Understanding Variables:


• Terms with 'x' are like variables - they're the unknown numbers we're trying to find


• When you see '2x', it means 2 times x


• A minus sign in front of x (-x) means negative 1 times x


Verification:


• Always check if your answer makes sense in the original equation


• Substitute your solution back to verify

Pro Tips for Better Results

Formatting Your Input:


• Use spaces between terms for better readability


• Good: '2x + 3'


• Avoid: '2x+3'


Troubleshooting:


• Double-check your parentheses and signs


• If you get stuck, click 'Show Steps'


• Practice with similar problems to build understanding

Common Questions

Invalid Format Error:


Make sure you're in the right mode (Solve or Simplify) and your equation is written correctly.


No Solution Exists:


This happens when the equation can't be solved, like when you have '0x = 5'.


Using Decimals:


Yes! You can use decimals in your equations.

Example: '2.5x + 1 = 10'

Examples with Solutions

Solving Equations:


• 2x + 3 = 7
