Linear Equation Solver
A linear equation in one variable has the form mx + b = c. The solver isolates x by subtracting b from both sides and dividing by m, showing each operation. It also handles the special cases where m = 0, which give either no solution or infinitely many.
Frequently asked questions
What form of equation does this accept?
It solves mx + b = c. Rearrange other linear equations into this shape, collecting the variable on the left.
What happens when m is 0?
The variable disappears: the equation has infinitely many solutions when b = c, and no solution otherwise.
Can the answer be a fraction?
Yes. The result is shown as an exact decimal, rounded only to remove floating-point noise.
