Solve ax + b = 0 for x, showing the solution and verification step.
A linear equation ax + b = 0 has exactly one solution: x = −b/a. This calculator solves any first-degree equation in one variable.
Linear equation
x = -b / a
If a = 0, the equation is not linear — it becomes b = 0, which is either always true (b=0) or has no solution.
Yes — rewrite as 3x + (5−11) = 0, so a=3, b=−6, giving x=2.
