THE IDEA BEHIND THE ANSWER

A formula you can follow.

ax + b = cx + d → x = (d − b) / (a − c)

Use expanded linear terms, decimals, plus/minus signs and one equals sign. Parentheses, fractions, multiplication signs and powers above one are not supported.

GOOD TO KNOW

A few helpful details

How do I use this calculator?

Enter linear equation. Choose any available mode, then select Calculate. The example numbers are a starting point you can change.

What if my input cannot be calculated?

A message explains what to change. Previous results are cleared when you edit an input, so the answer always matches the values you calculated.

Are my values sent anywhere?

No. These tools calculate locally in your browser, without an account. Displayed numeric results are rounded; these tools do not provide arbitrary-precision arithmetic.
