Linear Equation Solver

Solve any single-variable linear equation of the form ax + b = 0 for the unknown x. The simplest non-trivial equation in algebra, this is the building block for systems of equations, slope-intercept lines, and almost every applied modelling problem.

Linear Inequality Solver

Solve linear inequalities of the form ax + b < c (or ≤, >, ≥) and express the answer as an interval or number line. Use it when solving algebraic inequalities in coursework or real-world constraint problems.
