Linear Equation Solver
Solve equations in the form ax + b = c and see the algebraic steps.
What this solver does
Enter the coefficient of x and the two constants. The solver isolates x and shows the two basic algebra steps.
Special cases
If a is zero, the equation may have no solution or infinitely many solutions depending on whether b equals c.
How this resource works
For ax + b = c with a ≠ 0, subtract b from both sides and divide by a: x = (c − b) ÷ a.
