Equation solver

Batch 6: evaluate numeric expressions, solve equations/inequalities/systems, approximate numeric roots, and plot basic graphs of f(x) in x.

Enter expression, equation, inequality or system

Equations/inequalities in x: use + and - only, no parentheses. Systems: 2 or 3 linear equations in x, y (and z) separated by new lines or semicolons. For roots/graphs, enter f(x) using x.

Choose operation

Numeric results, equation/inequality solutions and system solutions with basic step-by-step explanations will appear here.

Tip: for a 2×2 system try: 2x + 3y = 7 and -x + 4y = 1 on separate lines.
