How to use this calculator
Choose Solve, Factor or Simplify and enter an equation or expression in the supported syntax. Review the resulting transformation and the original input together.
How to use the result
Solve accepts a single-variable linear equation with one equals sign, such as 2x + 3 = x - 1. It combines variable coefficients and constants on the two sides. Factor and Simplify operate on expressions rather than equations.
The displayed steps summarize the operation; they are not a complete symbolic proof. An expression that cannot be factored further may remain unchanged.
Assumptions and limits
The linear solver does not accept systems, quadratic terms or general nonlinear equations. Use one letter as the variable and keep input within 500 characters. Factoring and simplification depend on the supported symbolic-library syntax; an unsupported input produces an error.
Worked example
For 2x + 3 = x - 1, subtracting x and then 3 from both sides gives x = -4.
