FAQ
What is a linear equation?
A linear equation has x only to the first power, such as 2x + 3 = 11. Its graph is a straight line and it has exactly one solution when it is solvable.
Can I put x on both sides?
Yes. You can enter 5x - 2 = 2x + 7 and the calculator collects the x terms and constants for you.
What if I accidentally enter a quadratic?
If the equation contains an x^2 term, the solver will still handle it as a quadratic and report the corresponding roots.
Does the Linear Equation Calculator send my data to a server?
No. The Linear Equation Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
Solve 5x − 7 = 18: 5x = 25, so x = 5.
